Good But....
Sadly I feel that the engine is all thats going for the game really, the theme of something going wrong in a research lab and monsters take over has been done before remember half life, some of the monsters are quite interesting where as others arent in many areas of the game you feel that they are tossed right infront of you only to be riddled by some form of weaponry which can get a bit tedious especially when experiencing a low framerate.
The Hero is a man of few words just like the main character on Grand Theft Auto 3 who often stumbles in on conversions with high up shareholders armed with BFGs vaporising anything in there way. The main story is that you have come to mars as a soldier who would serve under a Sergeant Kelly, you are sent way down under the surface to investigate the disappearance of a scientist to find out what he has discovered and literally all hell breaks loose with spirits that posses workers and soldiers who would soon show up to greet you with a heavy blunt object or a hail of bullets and you journey through some of the weirdest atmosphere's ever seen in a game.
So I would say that I appreciate the game because of the effort gone into making the levels and environment, but it is sadly let down because of the unoriginality of the story and some annoying elements overall I give this game 7.4 because it is in no way a bad game It was just let down by a few things.
