Basic Strategies

The first wave includes large groups of Heavy robots at the beginning and end of the wave, but also support from the Demoknights. Use classes with weapons that do splash damage to take care of them quickly.

In the second wave the tank appears. Although it’s health pool is not so great as in the mission "Broken parts", and the other robots are less of a threat, send two players to eliminate the tank while the rest of the team concentrates fire on the robots. Giant Heavies in this wave are accompanied by Soldiers, which are armed with a Buff Banner and should be the main target for rapid destruction.

The third wave sends out several Super Scouts, which will spawn only one at a time (at the beginning of the wave), several Giant Demomen and large support of Heavies and Demomen. Use slowdown and/or bodyblocking to destroy Giant Scouts fast enough. In the last part of the wave, when all Heavy robots will die, three pairs of Super Scouts will appear in quick succession. Do your best to destroy them as fast as you can. Engineer bots won’t appear during this wave.

It can be a great idea to buy fire resistance before starting the fourth wave because Pyro robots will appear in large numbers. However, these robots cannot deflect projectiles and are much easier to destroy. Tank will wheel through the wave when most of Pyro-bots will be dead. Use your upgraded firepower to take care of the tank faster. The last part of this wave includes two Super Scouts and several crit-boosted Soldier-bots, the latter have a slightly reduced damage output. However upgrading crit resistance will help a lot.

Do not allow Uber Medics to use their charges on the fifth wave and put some money in resistances before starting this wave: large amount of Soldiers, Giant Deflector Heavies and crit-boosted Bowmen can easily make short work of you. Consider having a Demoman to take care of Medics and a Heavy to destroy Giants faster.

Be extremely careful when fighting Giant Medics on the sixth wave, especially if they are healing Giant Burst Fire Soldiers: their ÜberCharges can refill their lost health and make them indestructible for eight seconds and their invincible patients can easily kill you and your teammates. Consider having a Demoman, Sniper or Spy, which all excels against Giant Medics and Uber Medics, which appear in the end of the wave.

Consider having a Pyro for the seventh wave due to large amount of tanks, which will allow you to concentrate firepower on robots. With a large amount of money at this stage, this wave shouldn’t be too difficult and having a Sniper or Demo to kill Uber Medics will be helpful.

The final wave introduces the Captain Punch, the Giant version of Steel Gauntlet with a very large health pool, health regeneration and ‘One punch-One kill’ Gloves, so don’t stay too close to it. Use your firepower and Critical Canteens to destroy this boss robot as fast as possible, but beware of support Snipers and Spies.
