Hah, I just gave it a shot. It's not bad... pretty much like those Lego Star Wars type of games. It's got 2 player co-op too. If I had to compare between this and the Lego games though, I'd say the Lego ones are leaps and bounds better due to the controls being more refined. The moves in this game just seem very stale.
I nabbed the last Marvel Super Hero Squad game because it looked EXACTLY like one of those Lego type of games. I deleted it after about 1/2hr. Utter pap. Boring gameplay with just wave after wave after wave after wave of the same naff enemies. Unless they've improved things a lot with this one or you are a serious Marvel fanboy then save yourself the bandwidth. Yeah, yeah, it's aimed at kids but so are the Lego ones and they're good fun. Don't inflict it on ones so young who don't know any better
