As far as Serious Sam games are concerned this game is a disaster. As far as FPS games in general are concerned it's not bad. Unfortunately though, it does have that great lineage and it's no good pretending other wise. Enemies are stupid, vehicle sections are silly, levels are small, secrets are not funny, game is not funny, some weapons are downright absurd (parrots anyone?). Such a disappointment, compared to the previous installments, back in the days before things were ruined by pathetic console newbies.
On the plus side, this game does have a few nice bosses, good graphics (although the performance can sometimes be below-par), the destruction of the environment can occasionally be quite satisfying. These things help drag it up from the pit where the likes of Dreamkiller languish. It's not enough to shoot it much higher though, no way in heck.
