Some dissapointing news today. Radical Entertainment Tim Bennison let out the dissapointing news that Prototype, an upcoming open world action game, will have to drop it's online cooperative mode so that the game can meet its 2008 release date.
Why was multiplayer cut from PROTOTYPE?
Tim Bennison: From its inception PROTOTYPE was planned first and foremost as a single player open-world/action game. Naturally, with Alex’s genetically mutated shape-shifting abilities, we started to explore what would happen if he were to sub-divide into two PROTOTYPEs and what kind of multiplayer gameplay we could create around that concept. We’ve been looking at this potential multiplayer idea much more closely as PROTOTYPE’s development has been progressing, and while it’s a great concept and gameplay bonus, our conclusion is that we won’t be able to pull it off with the same level of quality and polish that we’re aiming for with the original single player story.
The game looked to be an evolution of a Crackdown style game with super powered players unleashing destruction around a city. Prototype is still slated for a 2008 release. There is a possibility that a co-op mode will be added later as download-able content. We'll keep our eyes on this one for sure.

And it's not just co-op, all multiplayer has been excised in the interests of expediency as well.
