So i just discovered you can get the "They never knew what hit them" achievement, which is While on offense, win the match in less than 30% of the time limit. You can get this super easy, as you can go into free play by yourself (turn bots off) and just rush through the objectives on offense.

Cheap, but works.

Lol what a cheapass Tyler. I might try this. I have to contemplate wether I want to take the easy way out or not

I did it in a versus match, I was mowing them all down with my gotlung all heavy-TF2-style. Did it on the the plane level
