Hothead Games, best known for the DeathSpank titles, have another downloadable offering lined up for release on PSN and XBLA next week. Swarm could be described as something resembling Lemmings, but it's far more fast paced and action packed.
Rather than trying to keep your Swarm alive the objective is to keep the multiplier up by killing them off strategically through the course of the level, while keeping enough of the alive to progress. Check out our interview with Hothead's Joel DeYoung from GDC for more information.
