If you have a pair of dusty old tights around the house, why not shove them on your head and play Monaco: What's Yours is Mine? The game is already out on PC and XBLA, but as of October 21st, it will also be available via Linux.
Not huge news in its own right, but by being on Linux, Monaco has opened itself up to be playable on Value's new SteamOS. If this is not enough excitement, Pocketwatch Games have also promised plenty of new/free content for this version.
What this entails will be up to the budding burglars out there to imagine, but with the game wracking up a Co-Optimus score of 5 out of 5, there is little reason to stop you pilfering a copy of this 4 player co-op game yourself (except for perhaps your conscience).
