This game NEEDED. MORE. CONTENT. The gameplay is fast and fun with good shooting mechanics, an excellent movement system, and a good co-op experience. Unfortunately, it is hurt by a lack of things to do. They try to go for an ever changing world approach but it falls flat because there simply isn't many new things to do after the quite short main story is over. It's possible insomniac intended to support this game more after its release before the sony buy-out.
