There's no word on when - other than soon - but we're told the demo will consist of the Outpost campaign level, playable alone, in split-screen or using Live co-op, as well as new multiplayer map Plaza.
People who already own the game, meanwhile, can look forward to four new multiplayer maps - for an undisclosed amount of Microsoft points - and several free auto-updates, one of which will add eight new bot personalities.
According to MS, those will be judge bot, who goes after the player with the most kills; venge bot who goes after whoever killed him; DarkOps bot, who is apparently the 'baddest'; and bully bot who goes after Kristan-oops-I-mean the player with the least kills.
We'll let you know when those pitch up.
