Been there dun that
Ok first the aliens (covenant) attack the us space station, and you go on from there (i dont want to give away too much).... Now lets get with the program...
Pros
+ large veriety of weapons
+ Graphics that sure is GREAT like tony's frosted flakes
+ good sound and voice overs
+ the vehicles are really cool (scorpion pwns all!!!!)
+ The multiplayer is the best thing in this game
Cons
-Story line (been there done that)
- AI might get too hard for some people
-And AI can be quite stupid to some others (the enemies run often, exccept the really big ones)
- Mulitplayer is the only thing good about the gameplay
