Time for some freerunning. DoubleDutch’s SpeedRunners [official site] is a spiffy side-scrolling competitive platformer in which each player controls a superhero attempting to reach the scene of a crime ahead of his or her cohorts. It’s a game about running, dodging, jumping and – most importantly – swinging from a lovely grappling hook. It’s a splendid game, supporting local and online 2-4 player games, as well as solo play against bots. You can try it for free this weekend, starting now, and there’s a 67% discount should you wish to buy.
