The Castle Doctrine is a home invasion MMO - its alpha is out now

You can always rely on Jason Rohrer to create something different. He's previously given us the collaborative storytelling sketchpad that is Sleep is Death , and the infinite, recursive, procedurally generated shooter Inside a Star-Filled Sky . So that his tenth game, The Castle Doctrine , is an MMO about burglary and home defence is expectedly unexpected. It's available now as a pre-release alpha.

According to Rohrer , the game attempts to show the impact of an unknown thief intruding on your life. As such, players are anonymous. "Someone's put work into this house, y'know? Someone's amassed this collection of stuff that they've spent a lot of time on, and when we violate it we're actually doing harm to a person in a real way. The moral ambiguity of the whole thing is at the core of what the game is about."

The alpha is $8, and available for Windows, Mac and Linux. That price guarantees all future updates, and is 50% off the full release.

Thanks, Joystiq .
