I'm sure this title will receive many negative reviews. I, on the other hand, really enjoyed this title.
If you always wished that they had released a version of Lethal Enforcers onto the console systems, then this is the game for you. It's a really fun old-school light gun shooter. It can be frantic at times, but I really like the low-fi graphics and cheesiness of the presentation. The controls are pretty straight forward for a light gun shooter on rails. It's alot more fun with one of your buddies playing with you. There are additional mini games triggered by completing certain objectives (there's one mini game that reminded me of Crossbow, where you had to protect the civilians walking along the screen by shooting the dangers ahead of them).
The gore level is pretty high on the default so if you don't want your kids watching buckets of blood and parts flying around, you might want to tone it down.
Give it a try if you're into light gun games. Just be ready to take everything light heartedly.
Do you love action packed games that you can't stop playing? Don't get this game then. This was easily the worst game I've played for Wii. Sent it right back in the mail. Horrible controls, extremely boring, have to reload every two seconds. Rent Resident Evil Umbrella Chronicles if you like arcade style shooters, skip this game. House of Dead returns was ok also.
