When editors of Game Informer magazine teased that its next issue would boast one of the most surprising covers in the publication's history, the Internet went mad

Was the heavily rumoured Sony Smash Bros about to get an unveiling? What about the next Sony platform?

As is so common in the video game industry, most gamers let unrealistic expectations get the better of them. But the editors of Game Informer weren't exaggerating about the unexpected nature of their next issue. After all, we don't think anybody anticipated Obsidian Entertainment — of Fallout fame — to be working on a South Park flavoured RPG.

But they are. Written, performed and overlooked by series creators Trey Parker and Matt Stone, South Park: The Game is pitched as "a full-scale RPG for the PlayStation 3". It will be published by THQ.

There's more information on Game Informer's website, and, of course, inside the magazine. Click on through for more details.
