About the game
Boxes hold guns, bombs and knives, and your job is to open them and fuse two of the same into something stronger. Place a weapon in a slot around the boss and it attacks without you touching it again, so the real work is choosing what goes where.
Bosses such as the shark in sneakers, the wooden log drummer and the coffee hitman behave differently, and some fly into rage phases. A damage doubler or an auto-opener can bail out a weak setup, but the difficulty keeps rising and a sloppy arrangement stalls out.
