Is infamous 1 on xbox 360?

inFamous is for PS3 only, but prototype is VERY similar and is for Xbox 360 only.

^LOL who ever said that, is stupid at a really high level, prototype began by being for ps3, then it came out for xbox 360 so did prototype 2, and i have both prototype 1 and 2 for ps3, they are no where as good as infamous AT ALL
