Portal, and to a larger extent Portal 2, have inspired a new subgenre of puzzle games that emphasize cooperation with a dash of cheeky humor. Death Squared is a shining example of this cooperative puzzler genre, letting one, two, or four players guide little robot cubes around a series of increasingly challenging deathtraps.
Death Squared features a lengthy Story campaign consisting of 80 levels that can be played with two local players, or a solo player controlling two bots with one controller. For the latter, the single player controls each bot with a different analog stick (or keyboard setup).
That’s a lot of levels, but they’re designed to be bite-sized. Each level should only take a few minutes to complete, and that’s with a lot of trial and error.
