It looks like inFamous is about to sell a boat load of copies. According to the PlayStation Blog, after keeping this secret for a long time, Naughty Dog is tackling the task of creating a fully-realized multiplayer and co-op mode(s) for their upcoming title, Uncharted 2: Among Thieves.

And, as rumored, there will be beta of the game in inFamous, which will be of the multi-player mode and it will be releasing on June 3rd – inFamous releasing May 26.

However, the games’ full co-operative mode will be playable with up to 3 players: Nathan Drake and Chloe Frazer along with a third character. In addition, the co-operative story will be different from the single-player campaign and there are mini-bosses to top the levels off.

Also the game will have a five versus five death-match in its Multiplayer as well as a Capture The Flag mode called Plunder.

“Adding a multiplayer aspect to the Uncharted franchise is a significant step in the replayability of the game,” said Christophe Balestra, co president Naughty Dog. “Uncharted 2: Among Thieves will be the most impressive and ambitious game that Naughty Dog has done and we are thrilled to let our fans experience it this fall.”
