This is most likely the most intense shooter out there you can play. It is just plain, all-out fun either with the bots offline, or with your friends over the internet. If you're looking for non-stop action, this is the game to buy.
Graphics:
Simply and utterly stunning, which is not a surprise when it comes to the Unreal Engine. The game also runs quite well on mid-range systems too. Textures are great, visual effects are fantastic and the models are creative and flawless.
9.5/10
Sound & Music:
The sound FX helps to make this game so much more immersive. I have no complaints when it comes to the sounds blaring off on my speakers. The music is nothing short of original, and helps to pump you up for more action.
9/10
Gameplay & Playability:
As I stated before, it's just non-stop action. However, don't expect the most original stuff out there. It's not all that different from the original UT and UT2k3. I'm going to have to say that if you already own UT2k3, you're going to feel kind of ripped off in buying this game. However if you have the money, go for it. There is just enough originality and hardcore fun to keep up the pace.
The controls and interface/menus are otherwise flawless. Customizability is also there.
8/10
Conclusion:
If you're still not sure, just try out the demo. It has enough of the game packed into it to let you have a good idea of what the full game is like.
I give this a 9/10, subtracting that one point for the lack of originality between UT and UT2k3. I just didn't feel that I got my money's worth after already owning UT2k3. Perhaps the developers should have thought of some new weapons, and other interesting features (hey, I'm not a developer, don't expect me to think of something fun and cool to substitute into this game). In any case, if you want a lot of fun, this is THE game.
