Impfireball: Will throw the wrench at the first moving thing he sees. Will shoot at said moving thing if said wrench doesn't pass through.
Someone enters the room, and you instinctively toss the wrench at the movement. It strikes a man in a red-tinted doctor's labcoat and a big backpack, killing him. You notice a large man with a really, really big brass minigun behind him.
Enraged, the minigun-wielding man begins shooting at you!
Roll to dodge: 1
The massive bullets penetrate the outer layers of your armor with only some difficulty. There's a good chance you might get seriously injured if you don't stop getting shot.
