Without any warning, both Prototype games have made their way to the Xbox One. The Prototype: Biohazard Bundle consists of Prototype and Prototype 2 (with all of the DLC.) It’s worth noting that these games seem like straight-up ports and not Remastered Editions with enhanced graphics. In fact, the Xbox store’s page for the Prototype: Biohazard Bundle says that the Xbox One versions were ported over by FunLabs. FunLabs is a company most known for the games in the Cabela’s franchise. It’s understandable because Radical Entertainment is no longer around.
You can purchase the Prototype: Biohazard Bundle for $49.99. The games are unavailable to be purchased as individual titles.
