Summary: This game's only real redeeming factor is, obviously, DINOSAURS. The 'characters' are entirely forgettable, the 'story' is a boring rip-off, the graphics are unimpressive, and the gameplay is unimpressive. I did like that there was a decent diversity of weapons, many with alternate fire modes, but that's hardly sufficient to carry a game.
Summary: It's a fun and enjoyable game in the first couple of maps, then it look like any other FPS, with lame AI's and less of what makes the genre great, killing dinosaurs. I find the knifekill/scenematics good at first, but lame after a while. The stealth system is lame too, you can sneak around and make silent kill's.... In the beginning, then the AI notice you no matter what you do.
Summary: Killing dinosaurs sounds great. When you kill them with knife looks awesome 1st time and 2nd time, but 100. time too boring, scripted knife kills in third person view is sucks. The checkpoint system very bad, the AI is cheating, very hard to kill them. The graphics are not good. The game is linear.
