The player has 100 HP.
Health drink heals 30 HP.
First aid kit heals 80 HP.
If your current HP is above 1, any attack that would drop your HP to 0 will drop it to 1 instead, next attack is fatal.
Resets after healing.
Chainsaw psycho is an exception as he ignores this mechanic.

Melee weapons "power attacks" do 2x damage.

Your crosshair slowly reduces in size (exact time depends on the weapon) when you are standing still (you can still move the camera though).
Moving, getting hit, switching weapons, reloading and attacking immediately expand the crosshair to the maximum size.
The only exception is the submachine gun where shooting one bullet at a time only partially expands the crosshair, it takes 8 submachine gun bullets to fully expand its crosshair.

If an enemy grabs you, you can break free by either staggering (more on that later) or killing your enemy. Cutting off a limb counts as a stagger, too.
Tearing up limbs resets stagger since it also counts as a stagger.
Bosses can't be dismembered, not even on death. (Plus some blow up anyway on death like Meat Golem and Monstruous beast).

Base movement speed is 3 (1x) while moving forward, 1.8 (0.6x) while moving sideways, 1.33 (0.44x) while moving backwards, 4.2 (1.4x) while sprinting and 5 (1.66x) while dashing forward during a melee power attack.

In order to sprint you must be moving forward, you can sprint sideways as long as you're also moving forward but you can't sprint backward.

Dropping down to 65 HP puts you in the caution state which reduces your movement speed by 10% and dropping down to 30 HP puts you in the danger state reducing it by another 10% (for a total of 20% movement speed penalty).

Forward/backward and sideways movement speed are calculated indipendently so if you move diagonally (forward/backward and sideways at the same time) you can move faster than intended.
You can see this strategy used in speedruns.

You have 100 stamina.

Running depletes about 25% stamina per second so you can run for 4 seconds.
Stamina normally replenishes at about 33% per second so it takes 3 seconds to recharge fully.
Stamina regeneration is 4x slower while reloading weapons and shooting the submachine gun (about 8.75% stamina per sec).
Entering a room immediately replenishes all stamina.

There are various actions in the game that slow down your movement speed and stop your stamina regeneration.

When you run out of stamina you get exhausted.
Exhaustion lasts 3 seconds, it cuts your movement speed in half and stops stamina regeneration while it's active.

Getting hit cuts your movement speed in half, keeps your chrosshair expanded to the maximum size, prevents you from sprinting and stops stamina regeneration for 1 second.

You can't interact with objects or move while in a grab and your stamina regeneration is halted.

Stamina regeneration is 4x slower while reloading weapons and shooting the submachine gun (about 8.75% stamina per sec) and your movement speed is cut in half.

Actually, attacking with any weapon cuts your speed in half (with exception of moving forward during a power attack, the windup still cuts your movement in half though) and stops your stamina regeneration.

Also, the shotgun pump at the end of your reload animation completely halts your stamina instead of slowing it down for some reason, it's the only weapon that does this.

Switching weapons stops your stamina regeneration but doesn't slow you down.

All these movement speed penalties stack.
An example is reloading while exhausted which puts your movement speed to 0.25x or getting webbed by the giant enemy spider makes you 4x slower, plus the 1 second hit penalty since it counts as a hit even though it does no damage therefore putting you to 0.125x speed.

Most enemies have fixed HP (i.e. dogs always spawn with 30 HP) except for zombies and cultists which have 50-70 HP and 30-40 HP respectively.
Exiting and re-entering a room fully replenishes non-boss enemies HP and even regenerates lost body parts.
Zombies and cultists change HP each time you re-enter.

Enemies have a hidden stagger meter which, once full, stuns the enemy for a brief time (usually for about a second) and (usually) puts them in a cooldown.
This meter is increased by hitting enemies and changes depending on the enemy you're facing and weapon you're using.
If you have played God of War (2018) picture the stun meter, only hidden.

Enemies usually charge directly at the player (since they have nothing else to do) with the exception of some enemies such as zombies, dogs and the monstrous beast which turn around from time to time unless they're in cooldown.
Enemies have a cooldown after attacking or after a stagger where they either stand still or move sideways and backward (depending on the enemy) for a brief time (usually a second or two).
Be wary that the cooldown after a stagger is inconsistent though and sometimes won't proc.
Staggers themselves are also a bit inconsistent and sometimes won't trigger if you stagger an enemy JUST as the enemy starts an attack animation, major culprits are the cultists and it's likely an animation bug. The mimic is an exception as the stagger immunity during its attack looks intended.

Shooting galleries both last 60 seconds.
In the first shooting gallery:
2 points target spawns every 2.5 seconds and stays up for about 4 seconds.
3 points target spawns every 3 seconds and stays up indefinitely.
5 points target spawns every 10 seconds and stays up for about 2 seconds.
10 seconds target spawns every 12 seconds and stays up for indefinitely.

In the second shooting gallery:
2/4 points target spawns every 2 seconds and stays up for about 4 seconds.
3/6 points target spawns every 5 seconds and stays up indefinitely.
5/10 points target spawns every 8 seconds and stays up indefinitely.
10 seconds target spawns every 12 seconds and stays up indefinitely.

Here's some theoretical calculations for fun.

Let's take the first shooting gallery in consideration.
You can extend the time 24 times theoretically for a total of 300 seconds.
Theoretical most shots yo can achieve is 200 since the pellet gun shoots every 1.5s if you let the crosshair adjust.
Not counting the time it takes to aim and shoot the targets there should be 274 available targets throughout a shooting session (24+30+100+120=274).
Since you can only shoot 200 targets (remember that 24 targets are for extending time and don't give any points), if you aim for the most valuable targets, the highest possible theoretical score should be 542 (5*30+3*100+2*46=542).
However, this is impossible in practice since multiple targets can appear at the same and the longer the targets are up the longer their respawn time is delayed so therefore we can conclude roughly that it should be impossible to go beyond 500.

As for the second shooting gallery the same calculations apply:
There should be 271 available targets throughout a shooting session (24+37+60+150=271).
You can only shoot 200 targets (minus the 24 extending time) so the highest theoretical score is 1046 (10*37+6*60+4*79).
Once again, we can conclude that highest actual score would be a bit lower and therefore it likely won't go beyond 1000.

My high score is 227 in the first shooting gallery and 330 in the second shooting gallery.
If you got any higher, post it in the comments so we can see what the highest score in the community is. :D

Note that the stagger inflicted by most weapons is completely random within their range.
The knife, for eample, could do 1.15 stagger with one stab then 1.76 stagger etc. completely at random.

Drawing a weapon takes between 1s-1.75s.
Aiming requires you to stand still for 0.4s-0.8s for most weapons.
Reloading takes on average 2-3s.
Speaking of reloading, the numbers I wrote down indicate the time it takes for the weapon to actually reload and the time it takes for the animation to end in case you want to animation cancel.
The pistol and submachine gun shoot 3-10 bullets per second while the other weapons take a second or more between shots.

Some weapons have a random chance of scoring a critical hit, these don't do any additional damage but rather dismember the enemies if possible (usually it's only the head).
The pellet gun, knife and crowbar can't deal critical hits.
The pistol has a low critical hit chance (probably around 5%).
The shotgun and submachine have a moderate critical hit chance.
The machete has a VERY HIGH critical hit chance (I'd say AT LEAST 50%).
The magnum, dynamite, holy water and rocket launcher are guaranteed to dismember enemies.

Fastest aim in the game.
Only use outside of practice range is shooting electrical generators (to stun chainsaw psycho) and the red orbs thrown by the final boss. Useful in knife/melee only runs since it doesn't count as a gun.

Fastest melee weapon.
Not much use outside of knifing zombies to save ammo.

AKA the knife replacement.
This weapon is also mainly used to kill zombies as the power attack was specifically designed to stunlock zombies (or the other way around).
Not recommended with other enemies since it's the slowest melee weapon in the game.
NOTE: Deals more damage against skeletons as it's hinted in its description.
Basic attacks do 3x more damage (24 DMG instead of 8 DMG) and power attacks do 3.75x damage (60 DMG instead of 16 DMG).

Fastest draw in the game.
Its high rate of fire and stagger makes it actually pretty useful against any threat as long as you're fighting one on one. Two enemies is also acceptable but if you're going against 3 or more it's recommended to switch to another weapon.

The upgrade to the pistol.
One taps most basic enemies if all 8 pellets connect.
Its higher damage and stagger is however balanced by its slow rate of fire and reload (which is the slowest in the game if you're reloading all 6 shells).
If all 8 pellets connect with an enemy it tends to deals 20 stagger VERY consistently.
That's a guaranteed stun for practically all non-boss enemies.

The reliable boss killer.
Kills most basic enemies in one hit and it's a guaranteed stun for all bosses except the Lord of the Nightmare.
Pierces targets.
Very useful against the knights boss fight and shield skeletons.
It also one taps the insane woman if you aim for the head.

Most practical use is to blow up multiple zombies like the ones barricaded in the kitchen.
It just takes too long to detonate.

Most powerful weapon in the game.
Although it's explosive it doesn't harm the player.
In horde mode it's very useful to quickly throw one of these on the ground if you are getting stunlocked by multiple zombies.
Saved me a couple times.

AKA the zombie killer.
If you aim for the head you can kill em with 2 power attacks, a lot of the time just 1 if you get a lucky decapitation.
On top of being a stronger counterpart to the crowbar it's also faster.

The ultimate weapon, it's so incredibly versatile.
High damage, forgiving aim since you can spray with it, no cooldown between shots and it doesn't halt your stamina regeneration.
The only thing that keeps it in check is the slowest reload in the game (other than an empty shotgun).
It's ammo is not even too expensive so be sure to stock up.

The worst rocket launcher I've ever seen in a videogame.
Due to how incredibly slow it is, it suffers in the damage department since it takes too much time between shots not mention that it's not even the most damaging weapon in the game (which is the Holy Water).
Use it only for fun.

*the cultist actually moves faster since he can move diagonally like the player.
Since he's slightly faster than a sprinting player, his actual movement speed is likely between 4.2 and 5.

This is where I'm dumping all the animation speeds and other stuff cause I couldn't fit them all in the previous section.
Note that these values were collected by watching recorded footage frame-by-frame so take it with a grain of salt.

Overhead 1.2s, point blank 0.9s.
Can attack up to 3 times in a row (melee only).
Stands still during cooldown.
Cooldown lasts 0.1-1s.

A typical stagger lasts about 1s with some aggressive enemies like dogs and cavemen taking about 0.5s instead.
The zombies are the only enemies that get staggered for 1.5s to reflect their slow nature.

After the stagger (and attacks, we'll get to it), most enemies stay in cooldown for about 1-2s to give you time to either adjust your aim or make some space and, again, some enemies are more aggressive staying in cooldown for only 0.1-1s in order to put pressure on you.
Examples are the insane woman and Meat Golem.
Only the knights stay in cooldown for more than 2s to balance the fact that you're dealing with multiple opponents, as previously mentioned, otherwise knife only runs would be practically impossible.

An attack animation can be considered of average speed when it lasts for about 1-2s and/or hits at point blank in about 0.5-1s which mostly consists of generic swings by enemies such as skeletons, cavemen and satyrs.
Attacks can be considered fast when they last less than 1s and/or hit at point blank in less than 0.5s such as bites from dogs and spiders and most importantly grabs from zombies which take a speedy 0.1s to latch onto the player, nothing else comes even colse.
Lastly, the slow attacks are either hard hitting charged attacks that you want to avoid such as the Meat Golem's cleaver and the axe satyr/Executioner's charged overhead or ranged attacks in order to make them less frustrating/BS such as the ranged knight's arrows and spider/Giant (enemy) spider's venom.
These last more than 2s and/or hit in more thank 1s which is usually ample time to react.

Something to add while I'm at it.

Slowest enemy in the game.
To compensate, it's moderately bulky and it grabs you FAST, leaving you exposed to grabs from other zombies for quite for some time which is especially dangerous in horde mode where they're plentiful.
Best enemy to use pistol ammo and dynamite on since its weakness is range/mobility until you find a crowbar/machete which can stunlock it with power attacks.
Don't be afraid to pull out the shotgun if you see yourself about to get surrounded.

One of the fastest enemies in the game, escpecially early on.
Melee is impractical due to their low position and fast movement.
To compensate, it has the least HP in the game.
Best to use a shotgun when they're in groups.
If you're fighting one on one, a pistol is fine since literally ANYTHING can stunlock a dog.

Fast, hits hard and from almost anywhere.
To compensate, he has the second lowest HP in the game.
The only reliable strategy I found to use the shotgun and colse the distance by either moving to a cover close to them or let them come you and then one shot them which is is quite to do since you only need to land about half a the pellets of a shot.
Aiming with the pistol can be quite finnicky since getting shot messes up your aim and he can keep hitting you which leads you to never landing a shot.

Most fun enemy since in can come in so many variants.
1-handed weapons don't do much damage so don't panic and just stunlock it with the pistol.
If they're in a group, whip out the shotgun.
If there are multiple skeletons and some of them have shields, prioritize those without it since shield skeletons are quite slow and you can easily dispatch them later without the other skeletons running at you.
If you're feeling bold, you can also use the crowbar to get rid of them in 1.2 hits...

One the bulkiest enemies due to its large health pool and lack of weak spots.
Its weaknesses are not immediately apparent but they're quite exploitable.
The melee attack hits very fast but deals little damage while the venom hits quite hard but takes a very long time to charge.
For all these reasons I think it's smarter to just straight up run past this enemy since by doing so you'll avoid wasting tons of resources, you should hope they go for a venom spit since this will get them stuck in place and put even more distance but if they go for a quick bite you'll only take minimal damage so the cowardly option is a win/win in my opinion.

Fastest enemy in the game.
As usual, this is compensated by low hp and damage.
Unlike dogs, however, they're easier to hit since they're taller and always run in a straight line.
Even a pistol is enough to deal with them, just shoot them once to stop them in their tracks and then take time to aim for the head for a swift kill.
Even in groups, they're not too much of a threat which is a bit odd for such a late game enemy.

Toughest enemy in the game, you'll mostly encounter it in randomizer and dungeon escape mode.
Using big weapons such as the submachine and magnum can be worth it due to their large health pool, shotgun is fine too but you have to rely on scoring critical headshots which can be inconsistent.
The ram attack can get you by surprise and cause you to miss a shot but don't panic even if it hits you since it's least damaging attack in the game.
Just sit there and wait for the perfect shotgun/magnum one tap headshot.

A bit weaker than its axe counterpart and more reliable to kill with a shotgun blast (if you land all 8 pellets). Plus it deals very little damage to balance its ranged nature.
Not much to say honestly, just say in cover to kill other threats first and then dispatch it fast.

Second slowest enemy in the game.
It's basically a weaker zombie, it has less health and damage than a zombie in exchange for slightly faster movement speed.
Just stunlock it with a pistol and move on.

First uncommon enemy.
Its high health pool and lack of weak spots, plus its stagger immunity during attacks and sursprise factor almost guarantees you're gonna get hit once.
After that, it's most likely guaranteed to die before it attacks a second time if you're using weapons such as the shotgun, so all in all just an annoying enemy due to its unavoidable hit.

Second uncommon enemy.
She's fast, aggressive and you fight her in a tight space.
Quite threatening if not for the fact you can easily sneak up on her and plant a magnum bullet before she even notices.
Feels kinda cheesy but you gotta do what you gotta do to survive.

Last uncommon enemy and clearly ripped straight from RE4.
It's necessarily advantageous to confront it since it takes a lot of resources to kill it plus it's moderately slow but if you have to I suggest ripping off a leg with a magnum shot to further slow it down and shoot it before it regenerates.
If it DOES regenerate just repeat the magnum amputation until it's dead.

The introductory boss, therefore quite simple simple in design.
He hits hard but slowly and is quite easy due to its CHONKY model.
Remember to aim for the head for that juicy DOUBLE damage.

A step up in complexity, testing your capability to fight multiple foes at once.
Honestly the easiest strategy is to stand behind cover from the bow knight(s), line up the melee knights and thenk kill them the magnum since it pierces targets.
After that you can calmly use the knife/pistol to dispatch the remaining target(s).

The gimmick boss.
Quite intimidating at first until you realize you can stun him with the electrical boxes and finish him with 2 magnum shots and a shotgun blast.
In horde mode, it's a different story though.
Have a magnum or holy water ready to stagger him and finish him off IMMEDIATELY before other enemies close in on you.

A spider but giant, that's it.
Ok fine, it hits slightly harder, its bite is almost unavoidable due to the spider's humongous size and it can immobilize you with a web (but honestly you're better off if you shooting instead of freeing yourself since it takes a long time anyway) but seriously that's it.
Just mow it down with a combination of shotgun, magnum or holy water.

The most annoying enemy in the game, basically a dog on steroids.
The game recommend you to run from it and for a good reason, he's WAY too hard to hit.
The magnum takes too much time to aim, the shotgun will miss some of its pellets due to the slow size and the pistol takes too long.
The only feasible option is usually to just use a holy water flask since it kills the boss and you'll get it refunded (plus other goodies) anyway.

The final boss in the gameand a bit disappointing to be honest.
Its red orb is slow and wasy to shoot down while his sword attacks can literally be dodged by walking sideways, not even running...
Due to this any approach is viable even just using the knife.

The side content boss and clearly ripped straight from SH2.
Due to the nature fo Dungeon escape mode, he functions more like a tougher enemy than a proper boss.
Sports a ranged attack and a couple melee attacks plus moderate speed.
Just bait his attacks and attack him during his cooldown.

The upgraded Executioner.
Same HP but faster and with a deadly multi-hit attack.
Other than that the strategy doesn't change much.

Thanks for reading!
Hopefully this guide helps you with understanding the mechanics of the game and better face the harder challenges, especially randomizer and horde mode.

Any feedback is appreciated since I want to make my guides as helpful as possible and if you have any questions, leave it in the comments.

Fingers crossed to a sequel to this amazing game!
