This is nothing like an actual stress ball. It doesn't give at all, and its total invincibility gives you an enormous sense of dissatisfaction. This game only makes you angrier. 0/5
I spawned a Blackout and whirled it around for a bit to get a feel for how it weighed. Then I slashed a doll down his right arm. His arm fell apart into three jagged pieces and he sustained a major head injury. He wobbled a bit, then fell over. I thought to myself, "yeah, he's dead" but then his corpse started snoring. He wasn't dead. He had fallen asleep. Kudos to him for being bored by a machete to the head.
There's a random difficulty spike at the level with Sgt. Johnson that makes it almost impossible to beat. Still haven't gotten an end score of better than -1.
