March 24 will witness the release of Team 17's handheld Worms-a-thon Worms Open Warfare. Heading to PSP and Nintendo DS, it sees a return to the series' trademark 2D gameplay of old. If you've had your head stuck underground for the last ten years and have absolutely no idea what classic Worms is, well, it's all about two teams of Worms, armed with ridiculous weaponry, kicking the crap out of each other in a bunch of destructible environments. Check out the new Worms Open Warfare PSP screenshots we've uploaded and prep your exploding sheep, ready for imminent deployment.
