CSR-Studios' top-rated XBLIG survival horror game Dead Pixels has updated with expanded content and a number of significant changes and fixes.

New to this update are the "Last Stand" and "The Solution" gameplay modes. The game also now includes a new "hardest" difficulty level, which is apparently quite the challenge. Other changes include upgradable melee damage, stat rebalancing, and an array of bug fixes.

"I hope you enjoy the new modes," developer CSR-Studios notes. "I tried to mix things up with them. If you don't like them, they were free and the original game is still there for you to play, so don't get too angry." Man! No matter how the new content stacks up with the main game, it's hard to imagine anybody giving these guys grief over a free update. Don't do that, if you're planning on it.

Dead Pixels is priced at 80 Microsoft points ($1).
