Maybe it could have achievements like, "Oops" when you fall and kill yourself, "Close" when you kill someone when you have 10 hp, "Phew" when you kill someone when you have 5 hp, "lol I HAD 2 HP!" When you, kill someone with 2 hp.
It seems weird that your bullets always hit the enemies and never hit your teammates, you are in a 2-D world where your bullets don't hit your teammates when you shoot them. -.-''
I agree with frafor. Why cut your hand off? If a handsaw is sharp enough to cut through bone, why isn't it sharp enough to cut through metal? I mean, the computer may have more time to punish you, but heck, a scar on your hand is better than not having a hand.
+ If you hate when you are level 25 and a level 2 comes in and you OWN THEM. Then they call you a n00b hacker who sucks dick and that they are way better than you.
@GriffinWing Just leave it on the hardest arena area you can get to, put it 1 area back and put it on hard difficulty, then just put auto-attack on and close the laptop/turn off the desktop monitor and just go to sleep. Or watch a movie. Or DO SOMETHING.
