I've always been very skeptical of the Worms games on consoles and portables. It just seems like they don't transfer well and given the critical failure of last year's Worms Open Warfare it seems like the series was doomed for portables. I'm happy to say the Open Warfare 2 is definitely a step up and initial impressions lead me to believe this could be among the most cherished of all titles in the series! Between a good single player campaign and an extensive online mode the game can please everyone - even with single cartridge play!
IGN has posted a good review as has GameSpot. So if you're looking to kick some ass using the classic bazooka or if you prefer the more exotic Buffalo of Lies check out Worms Open Warfare 2 for the Nintendo DS and PSP.
