Obtaining Mann vs. Machievements

.executioner In a single wave, kill 15 bomb-carrying robots in a row before they level up. Difficulty: Hard How to obtain: A robot will "level up" by taunting while carrying the bomb, bestowing upon it a series of buffs that make surrounding robots harder to kill. If a robot picks up the bomb, immediately kill it before it taunts. If the round has a relatively small number of robots to kill, consider just singling out the carrier so that other robots can pick up the bomb.

Balls-E Destroy the tank during the final seconds of the bomb being deployed. Difficulty: Hard How to obtain: As a loose rule, a tank should be at least halfway destroyed by the time it reaches the halfway point of the map. Should it manage to maneuver past your defenses to the drop-off point, your team should focus all of its firepower on it, using Kritzkrieg or Crit Boost Canteens in a last-ditch effort to destroy it.

Lower the first tank to a critical level of health without destroying it, do the same to the second tank, then have your team split up to simultaneously destroy both at once. Depending on the map, you may have to let the damaged first tank bypass your line of defense so that you can engage the second tank the moment it spawns.

Clockwork Conqueror Destroy a tank within 20 seconds of its arrival. Difficulty: Medium How to obtain: Once a tank spawns, your team should concentrate on destroying it, making use of Kritzkrieg or Crit Boost Canteens. Placing a Sentry Gun or Stickybombs near its spawn point can help deal extra damage at the beginning of the round.

Ctrl + Assault + Delete Destroy a sentry buster before it reaches its target. Difficulty: Medium How to obtain: A Sentry Buster has a great amount of health, so get help from your teammates to take it down. Deal as much damage as possible and make use of weapons with slowdown, such as the upgraded Mad Milk or Jarate, to prevent it from reaching the Sentry Gun. It's possible to place the Sentry Gun away from the battlefield to buy you time, but the Sentry Gun itself will need to contribute to the battle to cause a Sentry Buster to appear.

The ÜberCharge Canteen only lasts for five seconds, so this is best performed against a group of numerous weaker robots, such as Scouts.

Ghost in the Machine Use a canteen charged with 'Teleport to Spawn' and then kill the bomb carrier within 5 seconds. Difficulty: Medium How to obtain: If the bomb carrier makes it past your team and near the drop-off point, using a Return to Base Canteen can let you catch it in time.
