There are three games up for grabs on XBLA this week, and all of them offer something different. Encleverment Experiment (800, $10) seeks to test your brain power as well as the brain power of your friends (or random strangers on Xbox Live). Meanwhile NBA Unrivaled (1200, $15) brings arcade basketball with massive dunks (and odd character animations). Finally, 0D Beat Drop (800, $10) ... drops some rhythm-infused puzzle action onto XBLA. Watch the latest XBLA in Brief and see if any of them are up your alley.
