There is a time to fight and there is a time to survive........ this is the time to survive.
1) Good graphics and environments practically look real.
2) Amazing sound that will make you freak out when raptors pop out at you.
3) Some of the best looking blood and gore I have ever seen in any game.
4) Single player mode is pretty long and will have you playing for a while.
5) Good storyline that stays fresh from beginning to end.
6) Various creatures that you fight like raptors, T-rex, dilophosaurus, giant scorpions and they made a couple of extra creatures for this game.
7) Killing with the knife looks awesome.
Cons:
1) It is a tough game so you will have to be familiar with first person shooters to even stand a chance at beating this game.
2) Not too much of a variety of weapons but it doesnt bother me because you still can get a Knife, cross bows, Shotguns, pulse rifles, pistols, SMG's, and a couple of other guns.
3) Multiplayer lags a little bit.
