Not much of a survival horror game like previous games of the franchise, but it does well as an action packed shooter.
I'll divide this review into two parts
The Good: Extremely smooth and consistent gameplay mechanics. Responsive controls. Excellent AI, particularly that of your partner. Excellent online and local co-op gameplay. A very fun variety of boss fights. A large arsenal, not to mention costly. Ammo is occasionally dropped from dead majinis (name of the game's "zombies"). Very long campaign with a lot of replay value.
The Bad: Repetitive. Sometimes quite boring, pretty much a result from the repetition. Difficulty is very irregular, at one point you are fighting a large group of majini without a single scratch and next thing you know you get ripped apart by a bug (one hit kill).
Conclusion: A solid experience, that will satisfy an average gamer's need for non-stop action.
