Call of Duty World At War Demo

Call of Duty World at War demo was just released on the marketplace.

You get to check out one single player mission, and play with up to 3 friends for 4 player co-op over Xbox Live.

If you haven't checked out this title yet, be sure to download the demo, it is worth it. This is currently my favorite FPS on the 360, the multiplayer VS modes are great competition.

As a bonus, there's the zombie mode in the full game, where you and 3 friends defend an area from wave after wave of zombie onslaught - great fun.

When you're ready to pick up a copy of the game, find a cheap copy in the store: Call of Duty World at War Cheap Some of these are currently going for as low as $20.
