If you go on the Xbox Games Store right now you might be a little surprised to find both Prototype 1 and 2 on there.
Activision have certainly kept this one under wraps, as there was no official announcement for an Xbox One port of the game, not to mention any of its improvements – for example FPS or what content it includes.
You can currently buy the bundle for £39.99 with all DLC, so it might be worth buying it now.
