Beat it in one night tonight with a buddy in 2P local coop. It was awesome. Tense situations where we had 0 lives left and revives were successfully made, there were huge high-fives. The music and references to other games were awesome. We both live very close to Toronto, so it was awesome to pick out the references to real-world locations in Toronto.
Ex. Dee's (game) == Sneaky Dee's diner/bar
Leo's Place (game) == Lee's Palace concert venue
Castle Loma (game) == Casa Loma historical site
Sonic Wave (game) == Sonic Boom records
We were playing on Average Joe, and it was difficult, but satisfying. Story (what there was of it, at least.) made no sense, but that was for the best, since neither of us have read the GNs or seen the movie.
Can imagine that maxed out 4P on the hardest difficulty would still be a challenge. Kudos to anyone who can beat it 1P on the hardest difficulty.
Not many complaints about this game. Great game for local coop, which is something I feel is lacking on the PS3. Can't wait to get back to it for secrets.
