Three very different games on Xbox Live Arcade this week, gang. We've got the turn-based strategy of Greed Corp (800 / $10), the reverse platforming of Lazy Raiders (800 / $10) and the ... guitar-controlled platforming of Fret Nice (1200 / $15). Okay, so both Lazy Raiders and Fret Nice are basically platformers, but they're definitely different. Watch all the games in action in today's XBLA in Brief.
