Rambo + Jurassic Park = Turok
The dinos are incredibly well made in this game. They look how they ought to, move like they ought to, and fight like they ought to. Fighting raptors with your knife is awesomeness second to none. You can pull off speed kills with your knife, and it's pretty awesome. Overall, the concept is simple: You are a Rambo-esque dude and you fight bad guys and dinos in a jungle.
The gameplay has no negatives to it. None. The level layout is fine, the mission structure is good, you can't get lost (with a push of the L stick it brings up an arrow of where to go), and fighting is very, very fun. You are going from point A to point B, and that's how I like it. There are boss battles (T-rex anyone?) and frequent check points assure you that you won't have to do too much after you died. With the absence of aim assist, it really makes the game more realistic and makes every kill more rewarding.
The sound is pretty good. The weapons don't sound underpowered (like other reviewers say) and the jungle sounds really set the atmosphere. The voice acting is average. The music kicks in at the right time, even if it isn't the best in the genre. The graphics are great. The character models look okay, but the dinos and the environment looks fantastic. I haven't played the online, but from what I've seen, it won't replace CoD4 or Halo 3. Dinos add an extra layer of depth to it though.
Now for why I didn't give it a 10. I mentioned earlier that the gameplay is flawless, but the overall game is lacking in some areas. There is no splitscreen whatsoever, and that really stinks. It would be very fun to play, but there is only online. They could have fit it in there, but they didn't. Also, the previous Turoks were known for their awesome weapons, and this game has none. Just standard guns that are in almost every other FPS. The developers said they didn't put them in because they wanted it to be extra realistic, but that was a mistake. These are small complaints, so don't dwell on them because they don't affect the game massively. Note this is only 3 points away from a 10, and is truly a great game.
Turok is very underrated. Yes, some people might not like it, but I enjoyed it enough to recommend it to anyone who like FPS games. And shooting raptors in between the eyes with a bow.
