Been avoiding the thread for fear of spoilers, but I finally had a chance to play a decent chunk of this game. It's spectacular.
Plays like last-gen Bloodrayne, which is no bad thing for a budget hack 'n slash. There's enough meat to chew on to keep the combat engaging, but no finesse or subtlety. Love the balance between swords, guns and grenades; enjoying the upgrade system; and I think the healing works well. You have to keep an eye on the health bar, and you can't eat bullets, so you're forced to juggle ranged attacks with melee and make use of your arsenal.
Just finished the first job, but I've seen enough to recommend this to anyone who wants an amusing character action game with sweet PS2 feels set in the Marvel universe. Well worth the $50.
