I have it and I like it.. its a short game of just shooting people.. I have only played a few levels, but I like it, its nice. it has a 1.5 firmware updater in it, so your emulators should still be fine... I know mine are
yeah its a good game, better than the sequel that came out for the consoles. its pretty short thought, wish it was longer. the best part about it is the wifi multiplayer, i haven't found anyone else playing it yet, but it looks like it would be alot of fun.
