Zombie defense scheme: We lay piles of brains at the base of this and other similar structures and then fire small rockets at the rock above, toppling the rock and crushing the gobbling zombies below.
Some of you are no doubt about to suggest that we simply put the brains in a hole and capture those unfortunates whose cravings lead them to fall into the hole.
All I can say is, where’s the fun in that? I want to shoot rockets.
