Activision's slapped a firm June 5 European release date on open world action title Prototype.

That's four days earlier than in the States and three weeks earlier than retailer listings previously suggested, which is nice.

"Prototype lets gamers feel the power of being the ultimate shape-shifting weapon. You are the Prototype: Alex Mercer - a genetically mutated man without memory, armed with amazing shape-shifting abilities, hunting to discover what created you and determined to make those responsible pay," says the publisher.

"As Alex, gamers tear through a densely populated contemporary New York City moving with Parkour-style fluidity, consuming anybody that gets in their way...assuming their physical form, memories and abilities. Fueled by a three-way war between Alex, the Blackwatch (military) and a viral outbreak known as the Infected, players venture into a deep, dark conspiracy 40 years in the making."
