Dead Island isn't due out until August, but you may want to throw down a few dollars to reserve your copy now, as anyone who pre-orders the game at GameStop will get the "Bloodbath Arena" DLC free of charge.

If you don't pre-order the game, and eventually find yourself wanting the DLC, you'll have to fork out roughly $10 for it. Bloodbath Arena unlocks new survival challenges scattered across four different maps.

The pre-order edition of the game also offers a blueprint for a new weapon called the Ripper, which is a baseball bat with a saw on the end – we need a blueprint to make that? If you don't pre-order the game you won't be able to make this barbaric device, but friends who have it can use the magic of the Internet to send it to your PSN or 360 account.

GameStop is the parent company of Game Informer.
