Choosing a loadout for MvM is the part, where people tend to struggle in. So I want to show you which weapon combination is viable and which isn't. But first let's start up with some of primary weapons...

Honestly, you can't be wrong with any primary.

Shotgun and Panic Attack are good for self-defense.

Widowmaker can be pretty effective against Tanks when upgraded.

Frontier Justice is really good beacuse it can hold up to 35 revenge crits which is great for clearning medium-health robots.

Having Pompson 6000 equipped against Medics is usefull due to it's infinite ammo.

But the most usefull and overall greatest weapon for MvM is of course Rescue Ranger. I will talk about it more later...

The Wrangler tends to be the obvious choice, allowing a bigger damage output against Giants. It also allows the Sentry to take much more damage, but it should truly only be used against Giants or Tanks.

When picking the right wrench for the job these three should always come into your mind. All 3 can build a level 3 sentry and their downsides are not that big.

The stock Wrench is however best choice. It has no downsides and I found it most usefull than the other two.

The Southern Hospitality isn't greatest compared to the Jag and Wrench. Just keep yourself away from Pyros and you should be fine.

Jag is usable too but quicker building isn't really do much beacuse you can relly on your Upgrade Canteen.

This basic loadout is ideal in every situaitons. I have nothing to say more...
just...
don't use gunslinger...
stop it...
...now

You should always buy at least 1 Upgrade Canteen in case your ship would go down.
It costs 50$ each and it's super awesome! You can rebuild your nest quickest as possible with this thing! I wanted to say that you can waste with theese on a single Sentry. If your gun will get destroyed, it's just matter of time when robots will secure the area. In this situation, Upgrade Canteen is greatest thing on Earth.

1. Dispenser range




Per point of this upgrade will increase the activation range of your dispenser.
You should always buy this one first no matter what beacuse this thing will make your team stronger. It can support Heavy with ammo for a long range.


2. Metal Capacity




Each point added into this upgrade will increase your maximum supply of metal by 100.
At some point in the later waves you will be running low on metal and maybe your nest will get what was coming to it and you will need the metal to get your level 3 nest back.
It can be upgraded up to 600 Metal.


3. Building Heath




Robots will get better trough waves and your buildings will take more damage. For that reason it's good to buy Building Heath upgrade.
It can massivly expand your building health. Also when a Spy bot manage to sap your buildings and you have Building Health upgraded, it's also easier for you to get to them.


4.Swing Speed




This upgrade is amazing! Faster swinging speed = faster reapiring. I can really reccomend it.
It would come in handy when fighting massive waves.


5. Sentry firing speed




If there would be upgrade that would increase your Sentry damage output, it would be this.
But I reccomend buying only 1 point bacuse +10% is enough and remember you can increase it using Wrangler.




6. Rescue Ranger upgrades and Resistance upgrades
Having RR upgraded is a good move but you should always do that when you have everything for your buildings.
And upgrades on yourself....what else can I say? Every class need it.

and they are not strictly set.


Teleport Exit
You can put your exit also somewhere else but I found this spot to be effective the most.














Sentry and Dispenser
If robots will take left path, you can move it there. Be creative with your spots













Sentry and Dispenser
You can see that I took the high ground there. Leaving my Dispenser down for team...duh...

Teleport Exit
Like on Decoy, teleporer is good on that roof in the middle.














Sentry and Dispenser on left
Depends on where the bomb carrier manage to go.
















Sentry and Dispenser on right

Teleport Exit
I'd like to put my teleport into this little house














Sentry and Dispenser
Next two spots I found usefull on easier waves but I wanted to add them anyway.
Here's my gun under the balcony and Dispenser behind theese planks.














Sentry and Dispenser
If robots would like to take the other way. However if you want to use this spot, you should always think about backup.


















Sentry and Dispenser
If robots will destroy your nest, best way to setup is more back.
















Sentry and Dispenser
Of course it applies on the other side.

Teleport Exit
I'd like to put my Exit behind this rock like so.
Bigrock is a big map so if you have enough credits, you can build 2way teleport.














Sentry and Dispenser
This spot is very risky but gets the job done.














Sentry and Dispenser
I think this is ideal spot, you can however prove me wrong.

Teleport Exit
It works perfectly.













Sentry and Dispenser
My Sentry is looking down but also covers the flank behind it.
Dispenser can be also thrown down near your teammates.













Sentry and Dispenser
This is my personal favourite spot but I don't want to reccomend it just beacuse I saw a lot of Engies building there and failed really bad.















Sentry and Dispenser
Risky defending on A gate. Only usable when you have Medic with shield.















Sentry and Dispenser
You can also fall back and put your Sentry behind this little hill.














Sentry and Dispenser
Defending on B gate.

Teleport Exit













Sentry and Dispenser















Sentry and Dispenser
In case robots would push you from this area or when they would take the flank.

















Sentry and Dispenser
When your Medic and Heavy tries to defend the town, you can support them with your buildings.

Better defensive tool than the other primary weapons for the Engineer.
RR can be loaded up to 4 repairing bolts. It's obvious that this gun shouldn't be dealing damage so let's talk about...






Healing from distance
Very clever move being behind cover and healing your gun with RR. If you have upgrades, you can really see diffrence between destroyed Sentry and Sentry alive.

Teleporting buildings from distance
Not only in pubs, but also in MvM teleporting your buildings is awesome. Saving your gun against wave of robots or Sentry Buster really make your life easier.

Downsides
When hauling a building, you are now marked for death which means you are taking mini-crits. To avoid this, you shouldn't really move you gun by yourself, but with the Rescue Ranger.


Not only you can choose specific target for your Sentry, but it gains extra firing speed and bonus shield. To use this effective, try to target Giants, Tanks, Bomb carriers and other important targets. Due to insta-rebuilding, you can easily avoid the only downside: inacivity for 3 seconds after deploying a Wrangler only by redeploying your gun.

Sentry spots

• Be creative with your spots.
  
• Communicate with your team about them.
  
• Adapt on situations / waves.

Sentry Busters

• Try to get Sentry Buster out of your team so he can't kill anyone.
  
• If there's no team around your Sentry, make your life easier and use RR.
  
• If your Medic know what he's doing, let him chop Snetry buster with Ubersaw for Ubercharge.

Overall

• Your Sentry shouldn't be the main source of damage.
  
• Constantly move your buildings with the team.
  
• Keep your buildings alive using Building Upgrade.

I appriciate for your time and I hope you learnt something new here.
