So, we get this one for free and now they turn around and throw some DLC at us for 400MSP, thinking we'll just lap it up? Chances are, quite a few people did enjoy this one, but the whole thing seems pretty sneaky. I can guarantee they had the DLC planned when they chose this as the free game. Anyway, here's what you will get with the expansion:

• 5 Campaign Levels (Solo or Co-Op)
• 4 Multiplayer Maps
• New Playable Race, the Elect

No new achievements have shown up on xbox.com yet, so I'm not sure if this expansion will take advantage or some or all of the extra 50 points allotted to arcade games for DLC.
