Prototype

"An open-world game set in New York starring a shapeshifting man who can copy the appearance, skills, and powers of anyone he comes across."

I have literally just stumbled across this game in GameSpot. I have to say, just from the screenshots, this looks like a game I will love. Not 100% sure of the story, except for the synopses that I placed at the top of the page.

Another snipped from GameSpot explains that "Alex can also assume different shapes, most notably transforming his arms into wicked-looking blades which do a great job of slicing enemies clean in half. Another ability lets Alex use his accumulated biomass to create a thick armoured skin. Alex can also "consume" anyone he comes across--he can take on the memories and abilities of any person by consuming their biomass (thanks to icky Spawn-like tentacles seeping from his body). Not only can he take their abilities, but he can also shape-shift into that person, allowing Alex to sneak within his enemies' ranks and even get away unnoticed from any chaotic situations."

All in all though, this is definitely a game I am going to keep a close eye on.
