Warning!: This is my own take on how the events in Crysis went about. Don't say that it was supposed to be one way or another. I'll already know the events of Crysis. Warning!: There will be spoilers for Crysis 2 and 3. If you haven't played any of them yet, do so, they're great.
Alcatraz has, well, we don't really know what happened to him besides an impact into Equestria. You see, when Prophet took over the Nanosuit, Alcatraz lost control of his body, and everything about him. Now technically dead, the bio-soldier must find a new way to adapt to his surroundings.
