This is one classic arcade game and is perfectly suited to Wii. Complaints are that it is short and can be completed quickly, which it can, but it has replay value of enormous proportions.
There is plenty to unlock and with multiple paths there's a lot to see. Multi-player also adds a great deal of length to the game but even when you are without friends there is an online leaderboard using the Nintendo Wi-Fi Connection.
Simply put if you like playing action games you'll love it and it sets a moderately high standard for House Of The Dead Wii to match.
