The first week sales of Call of Duty: World at War have outsold Call of Duty 4's debut by more than 2 to 1.
This new info comes from gamesindustry.biz, who claim that 4-player co-op title World at War is also currently the top seller overall in the United Kingdom.
This makes perfect sense to us! Games with online co-op require co-op partners, and apparently there are plenty of those in Europe.
A quick search for North America sales rendered nothing yet; perhaps it's still too early, or maybe we just don't have the most advanced source.
Unsurprisingly, Guitar Hero World Tour and Gears of War 2 also made it onto the list, which can be viewed after the "Read More" link.
