Massively Fun !!!!!
look beyond the sometimes iffy visual quality (especially any cut-scenes with a certain sister; those eyes are so dead, she must be infected too), and you'll find a game that truly gives you the visceral experience of being a super-powered being. Most of the MARVEL characters that have made it to the big screen in the past couple of years are represented by proxy here: Spider-man (Black costume version), Hulk, Wolverine, even the Punisher makes an appearance here. Though the best ability is what i like to call a tribute to that original WILDC.A.T.S. team member, Warblade.
if you wanna know what it feels like to be a super-powered anti-hero, get this game. 2009 has still a few more months to go, but [PROTOTYPE] easily goes into my Top 5 of the year, if not the Top 2.
