Finally beat 26. You just need to remember that some guns can shoot through walls/floors when you're close enough to them, and avoid robots, but kill the human as much as possible.
I love the concept, it needs a lot of work such as chat, room locks, vote kicks maybe. I just can't ****ing stand some of the **** people do on this game.
Do wish there was a level editor of sorts.
Because the in-game levels are perfect the way they are, but I really like the game play outside the storyline.
