If Rock Band 3 didn’t have enough experience points for your tastes, then Iridium Studios may have the game for you. They’ve just released a new video detailing how to play their upcoming rhythm-RPG hybrid, Sequence, which has players juggling between three different note charts in lieu of the standard turn-based combat. The bizarre mash-up features a 28-song soundtrack, a robust inventory system and full support for guitars and dance pads. It’s a DDRPG! Can RPG elements provide the rhythm genre a comeback tour? Hey, it worked for Puzzle Quest! We won’t have to wait too long to find out though; Sequence arrive on Xbox Live Indie Games in April for 240 MS points ($3).
