Here's some potentially good news for gamers hoping for a sequel to Xbox Live Arcade side-scroller Shadow Complex. It seems Chair Entertainment has begun to plan their next game.

"We're definitely working on...things," Chair co-founder Donald Mustard told MTV Multiplayer. "I'm just not going to tell you what it is...we're still evaluating in the design phase."

Given the commercial and critical success of Shadow, it seems likely they'd make another installment. It's possible they want to do something different first, though.
