The two-man team at Alientrap Software have announced their next project Capsized will be coming to the Xbox 360 in 2010.

This side scrolling platformer has a unique artstyle and setting, and will including numerous shooting and physics based puzzles along the ride. The game reminds me of the old Metroid games with a bit of Xbox Live Indie Games' Weapon Of Choice
with a dash of Halloween Harry / Alien Carnage.

Currently the game is being developed on the XNA platform, so it will likely appear on the XBL Indie Games, but the developer is currently looking to get through the Xbox Live approval process before turning to it.
