There are alot of great things, but there are also many parts where the game is lacking.
Graphics: Game looks like it belongs on an early gamecube game. The wii graphics are supposed to be a step up from gamecube but its hard to tell. While graphics arent everything it would have added to the experience to make everything a bit more crisp and brighter.
Sound: The sound of gunfire and monsters dying work for the game and add to the experience. Its not bad but there is definitely room for improvement.
Value: The character classes do add to the value of the game, but it is a bit repetitive. Playing alone is much different than playing multiplayer and both experiences are fresh.
Tilt: Overall it was fun to play and the storyline could be skipped. While there are some things that could be improved there are also alot of little things that were done correctly that save this game from being broken. It made good use of wii controls and the game was not frustrating, which is always a plus when using the wiimote.
