So I played through this with a friend in couch co-op on the Wii with the Wii Zappers immediately after running through House of the Dead 2 and, while I still had a great time with it, it was an obvious downgrade in most regards. The gunplay wasn't quite as satisfying and the bosses weren't nearly as good, however, I still ended up enjoying my time with it. It's worth a play for sure, it's just not quite as good as the game it's following up.
