Im not realy sure about this game but I did not like the game after a second playtrough.---Pretty short review---
The story is nice and some characters have some feeling in thereself.
The guns are not that great, there are not powerfull and pretty boring to use.
The campaign is great to play 1 time.
Killing dino's isn't my favorite but its fun.
It gets fast repetive to kill a dino but its for plain fun.
Enemy A.I. is pretty dump but also not dump they need to fight also vs the dino's to survive.
There are some great and fun bosses to fight with. Most of the bossers dont get repetive.
There are some puzzles to kill the bos monsters they get clever and are pretty hard to find out the first time.
There is some nice landscape so see at and the explosions are pretty nice.
There is also a multiplayer mode.
It is pretty fun like when your playing to other players online then you get also in battle with random dino's is annoying but fun.
There is a co-op mode to wich is also fun IF you are with 4 otherwise it isn't that fun and damn hard.
If you play this game for the first time then don't try the game allready on hard difficult.
It is very hard then when you play it on normal.
The realistic difficult is for people then played the game out and are very good at this game.
I think its impossible to play the game out on realistic and or hard but it can.
I would say rent it first but you porberly won't like it.
I did like it becouse i played it the first time when it came out.
