Performance related:

• Game is made on Unreal 4 engine;
  
• Game can be played on both DirectX 11 and DirectX 12;
  
• While game has a few bugs, it is quite stable (got 1 crash in 70h);
  
• You'll probably have a high ping. The servers are located in Hong Kong i believe.
  Gameplay related:
  
• Match is time limited (30min);
  
• Agents have their own abilities, but most of their gameplay is defined by consumables found in
• the match;
  
• Fiend gameplay on the other hand is defined by his abilities(kit);
  
• Audibles are the most important info(with aura reading items/abilities) to locate enemy/ies;
  
• There are a few things that are annoying game-related (charm switching, opening doors, picking up things);
  
• Hitboxes are terrible and many mind games uses exactly that flaw to be effective;
  
• Comparing to DbD window vaults are not that effective since fiend can vault specific window at the same time, and make it even faster than agents;
  
• Most loops rely on doors and holes in the walls where you need to crouch;
  
• There is a report system in-game, but i haven't seen any reportable behavior yet;
  
• Game is protected by EAC.
  Other:
  
• This game is like a porcupine - every needle of this animal (game) is a different lootbox. Game is literally flooding with paid lootboxes that are filled (mostly) with oversexualized skins for female characters. This doesn't change how you play the game, just the looks.
  
• You can obtain chest after a game - you open some of them with spirit coins;
  
• There is 0 verbal toxicity - you can't be offended if you don't know what your teammates are saying;
  
• There is built-in voice chat (as fiend you don't hear it(there is 1 instance where you can go into voip as fiend));
  
• Only 1 agent and 1 fiend are free to play from the start (Luo Fang & Spectre);
  
• There is a weekly rotation of characters to play even if you don't own them (5 agents and 2 fiends), however, they do not count towards ranked characters and you can't gain character/account exp while playing them (unless you bought them). Rotation changes between Monday/Tuesday (depends on time zone);
  
• You unlock characters with spirit coins (280k-880k for 1 character - while there is no upper limit of how many you can gain per match, max i got was something around 3300);
  
• Game rewards playing a bit everyday (easy daily quests, everyday login bonus, etc.);
  
• Game is 5v1;
  
• There are 4 maps so far (school, hospital, GKD office, and downtown);
  
• If a game is beyond hope there is an option to surrender. As far as I experienced in my 200h, players don't abuse it and surr only if needed (E.g. 2 players did not connect to match, 1 DC'ed at the start, and one of the last 2 playing games got downed and even moried in the first minute). To successfully surrender all alive players of respective sides must agree (press F9 to agree).
  
• Game is mostly written in Mandarin Chinese (with a bit of English translation here and there).

Words used in guide interchangeably, that has same meaning:

• Ward - thing agents needs to repair
  
• Spirit Coins - grindable currency
  
• Invisibility (Cloak/Shroud) - ability or item that makes you invisible
  
• Moni (Money) - either real money, or in-game currency
  
• Spirit Stones (Gems/Paid currency) - currency obtained with real money
  
• DbD (Dead by Daylight) - popular but neglected by developers game in the same genre
  
• Mist Form (Ghost Fog) - Fiends ability to reduce size of their hitbox on demand
  
• GKD (GKDID number) - in-game indentfication of your account
  
• Mori (Execution) - perma death for agents
  
• Terror radius (heartbeat) - sphere area around fiend where agents can hear certain sound
  
• Ulti (ultimate ability) - in case of agents: active ability | in case of fiends: R/F4
  
• LMB - Left Mouse Button
  
• RMB - Right Mouse Button

OLD GUI BELOW, IN PROCESS OF UPDATING.

Game modes:

• Casual - Standard Soul Dossier experience.

• Ranked - Standard ranking experience; unlock 2 fiends/6 agents to play it. You ban 1 character from opposite team before playing game (that is why you need at least 2 fiends). Agents have to pick different characters (that's why you need 6 agents unlocked). You can play ranked with temporary unlocked characters via coupon, but free rotation characters does not count. In rankeds, wards need 4 essence instead of 3.

• Werewolf in sheep clothes(arcade) - 10 players, 8 agents & 2 fiends (disguised as agents), quite much going on in-game. Agents need to repair 6 wards 5 times. Yes, this mode has voting (like in First Class Trouble or Amoung Us) where they can kick out someone. When there is speaking phase (everybody freezes for up to 1200s and talk who to kick), don't forget to skip talking (midde bottom of the screen when there is your turn to speak).

Balance Restored mean agents won; Balance Broken mean fiend/s won.

All boosters are applied to the numbers you see after game. If you got 350 account exp with 100% booster, without it you would get only 175.

They are add-ons that you can find in lockers or wardrobes or by grabbing and opening Paper Pigeons. They give various bonuses when used.

*the way I named these boxes does not match the actual translation, but I chose this way to make them more recognizable for the English playerbase
**There are a few non-event, non-grindable time-limited chests either available for 400 or 1000 Gems. They are quite straightforward (buy chest, maybe get the skin you want [unlikely], repeat) so I won't add them to the guide.
Boxes without |BUY 10| option will increase their cost each time you buy one, but you can't get duplicates from that chest.

• (unsure) You can sell only permament items you didn't use yet (they exist in equipment, but you can't equip them (Which indirectly means you need to buy some lootboxes anyway(damn free to play games with cash grabs from mobile games FFS)))
  
• All buy/sell orders are available ONLY in premium currency.
  
• A tax of 15% will be deducted from total amount of shards you made with selling item (after successfully selling it). If you sold item for 10000 shards, you'll get only 8500. #capitalism
  
• Item names are available only in chinese (a few of them have english signs, but you probably won't be interested in them anyway)*

How to look for sexy overpriced skin you don't have enough shards to buy (image version for kindergarten):

(these 2 currencies are ONLY visible when you navigate to wardrobe/exchange store)
I. Consumption coins (You get this when you buy things with spirit shards(1:1 ratio) and you can buy hairs that boost exp in-game)
II. Chips of Jade (Obtained via dismantling coupons/skins, very hard to grind - there is a special section at the exchange store for this currency; dismantling permament skins gives the most chips)


From the left:
-spirit shards* (paid currency)
-spirit coins (bloodpoints)
-ancient coins (other currency used interchangeably with spirit shards to buy cosmetics (it has a separate tab in wardrobe), but it is obtained via quests)
-[removed, needs updated image]

*Recharging an account with paid currency (soul stones) supports Steam Wallet. You go to the wardrobe and look at the top right corner. Blue shards currency has a small "+" sign on the left. When you click it, you can pick whatever amount you want to purchase, and then you'll be redirected to the steam purchase window (i believe you need to turn on steam overlay in-game to do that).

You can check how many (and which) slots suits take by looking what icons are greyed out.

S.C. = Spirit Coins Boost (always buy skins with highest bonus in this category (i think 21% is the most for suits and 8% for 1-piece clothing (max bonus you can get now is 37% with Su Qingli)
Acc. = Account exp bonus (so far account level has no bonuses for it - worthless bonus)
Char. = Character bonus exp (more xp points for characters you play - since they arew capped at 50th (in the future it will be 100) this is a diminishable bonus in long-term)

Generally, it is not worth buying lootboxes - RNG is against you. Odds are 99:1; 98:2; 95:5 or 90:10 against you (paid chests have better odds). If you are patient, buy clothes from the ancient coin market that rewards you with the highest spirit coins (yu ji outfit for example has 21%). Grind spirit coins while using them, then buy other characters faster. Exp them to get ancient coins character affinity rewards (up to 1500/character). Repeat.
*note* You can buy clothes for characters you do not own (useful for sales).
For some time now, ancient coin mall have skin rotation, which means only some skins are available at any given time, unlike previous system where you could buy what you wanted, when you wanted.

Agents suits are less rewarding, but overall they have more wardrobe parts and you can get higher bonuses. Qing Hong is a good example - you can get 25% boost for 17850AC (5-parts, without sale). This means you'll get 1% spirit coin increase for every 714 ancient coins spent. If you buy all parts with 20% discount this will drop to 571,2 (14280/25%) or 535,5 with 25% discount (13387,5/25%).

Table with few examples (prices does not include sale):
*A.C. = ancient coins
*S.C. = spirit coins

|x=s/b
|x - equation for A.C. cost to 1% S.C. boost
|s - actual skin price
|b - % set bonus (written without percent symbol, to get cost instead of percent)
|20% discount Yu Ji skin (21% boost) A.C.-S.C. ratio = (13900*80%)/21 = 529,52

[As you can see it is more lucrative to buy cosmetics when they are discounted.][knowyourmeme.com] Also, pay big attention to the price/boost ratio as sometimes its value may be illusory. Unless you buy skins only for $W4G. Generally, 8% for 1-piece and 21% for suits is the highest available bonus now.

*note* Currently the highest (at least by my research) yielding cosmetics for free players is Ge Yeongming doctor "set" with 3% katana. It is 5-piece clothing that costs 20400(full price) A.C. and gives 35% S.C. boost. Without discount ratio is around 582,86 (437,14 with 25% discount). While it is not the prettiest set of cosmetics, this character is very good for ranked and you may consider buying it just for hardcore grinding purposes. (this does not include 25% hair, which is not available to buy with ancient coins)

*note* Overall suiting for looks is a better option - hardcore grinding without any other purpose (and with ugly skin on top of that) will make you bored with game very fast.

There are 11 tasks that you can do everyday thet rewards you with small amount of spirit coins (they reset at the same time every day (5PM, GTM 0) - same time globally, but different local time (Monday)). For each task done you claim points which rewards you with bigger rewards (points are auto claimed after clicking daily activities tab but rewards do not auto claim, so they can be lost at reset if not taken manually with claim button).

They go as follows:

• (5p) open item chest
  
• (5p) open trickery chest
  you open this chests at wardrobe/tresure box/ red boxes at top right
  
• (10p) play 1 ranked as Agent (doesn't matter if you win, but you can't AFK)
  
• (10p) play 1 ranked as Fiend (doesn't matter if you win, but you can't AFK)
  
• (10p) login in game
  
• (15p) win 2 matches as Agent
  
• (15p) win 1 match as Fiend
  
• (15p) get MVP title in match
  
• (15p) play 2 games
  
• (25p) play 5 games
  
• (30p) play 10 games

You can score 155 points each day. They stack up to 1085 (7*155), but you need only 900 points to get all weekly rewards (130/day). This is the most reliable way to grind, so i encourage you to do them if you have spare time. Also, you can get up to 5000 Spirit Coins for them.

Rewards:

1. [150p/155p]1*compass; 10*ancient coins; 500*soul coins
   
2. [300p/310p]1*jade stone; 10*ancient coins; 500*soul coins
   
3. [450p/465p]1*compass; 50*ancient coins; 1000*soul coins
   
4. [550p/620p]1*night vision; 50*ancient coins; 1500*soul coins
   
5. [700p/775p]3*compass; 80*ancient coins; 3000*soul coins
   
6. [800p/930p]1*jade stone; 100*ancient coins; 3500*soul coins
   
7. [900p/1085]1*coupon; 3*compass; 5000*soul coins

In total, claiming every weekly reward you'll get: 8*compass; 2*jade stones; 1*night vision; a 7-day coupon; 300*ancient coins; 15000*soul coins. Kinda garbage rewards, but grinding ancient coins that way is your fastest and most reliable way to get nice skins.

*note*
Daily quests that refer to play/win can be done only at normal or ranked mode (or ranked only in case of 2 quests). Also game that was lost due to surrender vote, also count as game played (but not won).

*note*
You don't need to play any rankeds to get all weekly rewards.
If you'll do all other tasks which give 945(135*7) points all together, you will still be able to get all weekly rewards without need to rush to buy characters (so you can play rankeds).

In-game calendar that resets every day at the same time. You click highlighted day for x days to get rewards shown on the right. While they are written in Chinese, you can see arabic letter and how many days you need to obtain them.

Your daily streak is shown as number in red circle between board and rewards column (you don't need to claim them everyday, just enough each month).

Rewards reset each 1st of the month, and you can score them again repeating the process.

You can press TAB (by default) to show this overlay in-game.

Souls(Health)
Behind HP bar stands numbers (not sure how much HP you have, but you'll get downed around 3rd hit). When you are downed other agents can heal you so you can get downed again. While downed you can crawl, and you do not bleed out, which means you will be crawling until someone heals you up, or fiend mori you (they tend to do it ASAP if they can, so intentional slugging is not a common practice). Agents can be moried 2 ways:
-If they have the corresponding element when downed (Metal→Water→Wood→Fire→Earth[Agents can be executed in this order, but they gain elements in random order, can be wood, can be earth, can be metal but each agent has only 1 element predefined when game starts, but they are not shown])
-If all their psyche points are drained (this is only case when they can be executed out of order)

Stamina
You use it for running, sliding, and sprint jumping (you jump higher when sprinting). Slow vault, crouching, or walk-jump does not consume any stamina.

Ultimate
Shows you a cooldown on your active ability (every agent has only one).

Item
Most often compass - you use it without consuming, but there is waiting time between uses.

Flashlight
It is infinite, and it slows(?) fiend when you light it on him. You can flashlight flick tho (it is much slower than in DbD).

Map
Not shown in the tutorial level, but useful for beginners to get around more easily.

Ward progress
Shows you which ward is repaired and how much.

Essence stored
You can store up to 2 essence - they are for repairing wards.

Debuffs (Psyche?)
When red, you are afflicted by specific debuff.

There are 7 of them:

• [Fú Shī] | 伏失(head) - you will lose sight and see only a small area around you periodically.
  
• [Fēi Dú] | 非毒(throat) - chance to lose 2 psyche points instead of 1 when attacked.
  
• [Tūn Zéi] | 吞贼(lungs) - unable to be healed by teammates.
  
• [Què Yīn] | 雀阴(elbow) - increase time to repair generator and open paper pigeons.
  
• [Chú Huì] | 除秽(pelvis) - HP won't regen automatically, but can be healed with items.
  
• [Shī Dǒu] | 尸狗(hand) - can't be revived for 20s after knockdown.
  
• [Chòu Fèi] | 臭肺(knee) - reduced movement speed.

---

Wards (generators)
This is your goal to repair them. They have different models and a bit different light color which makes it easier to differentiate one from another. One essence can repair only its respective ward (and trigram ward which accepts every essence). It takes 20s to repair it (or more), and you lose whole progress when canceled(by any means). You need to do it three times for 3 different wards to win a game. Fiend will always see your aura when you are in process of repairing ward even when cloaked by charm or ability.

Elements
They are used for few things so try to remember them ASAP (because proper english translation might take a while).
