Excellent game, well worth the money!!

The game costs $20, it is known throughout the world, they are thinking of coming out with a movie for it. You can get a free trial and try it out from microsoft.com. Need any more convincing?? Oh, ok

Action
There is alot of action in the game, there is no swearing in the game, just alot of sci-fi stuff. There are some great ideas that were put into the game as well, taken from many different great sci-fi books (or so they say).

Plot
The plot is very good, as with all my other reviews I won't reveal anything specific, but believe me once you get into the plot and start enjoying the action, you won't be turned back and you'll be coming back for more.

Multiplayer!!
Yes multiplayer, either with LAN (Local Area Network) or just online, you can create a game online (host) easily enough, just go to internet, and create game, choose the different maps and settings and you're off! The multiplayer is absolutely addicting, especially if you find some games on there without people having modded characters (They nearly never die)

Sci-Fi
If you like watching the Sci-Fi channel and are expecting aliens to land in your yard really soon then this game is for you. One such example is the AI Cortana in the game, she helps you throughout the game and is basically a computerized person who is holographic and can fit into your helmet because she's a computer chip for storage options :)

Computer Requirements
Keep in mind that this game is meant for an average or above average PC, but much more of the latter, make sure you have a fast CPU and a great video card for the best effects and for you people that like the "gaming experience" get some good speakers and crank it up :)
