From the review:
"Did you ever play Pikmin and wish you could just squish and maim the cute little buggers? Well, with the recent release of Swarm, now’s your chance! Okay, so maybe these aren’t the colorful little Nintendo characters and you’re not Captain Olimar, but the blue, rotund Swarmites are a good alternative. And although you need to keep them alive to complete various missions for you, you’re going to lose a heck of a lot of them, oftentimes on purpose. Even the main menu lets you take a crack at killing Swarmites as much as your sadistic heart desires."
