These other reviews are crap. I got the game on Saturday, the 3rd, and I have ample experience with it... It's fantastic
Gameplay: 10
It has so MUCH variety amongst the regular run and gun shooting. Within the story you play with 3 or 4 different perspectives. An arabian president, a SAS soldier, a USMC soldier and an unknown special forces soldier in a huge airliner rescueing a hostage... It's weird, but awesome. Also, there are simple in game perks... Like, if a dog attacks you, it jumps on you and you have a fraction of a second to press the melee button at the right time and you'd grab it's head and snap it or... if you don't time it right, it'll rip your throat out and... you die. The MULTIPLAYER: Is fantastic, unlike many, many, many shooters with powerups and stuff, it's EXTREMELY balanced and so fun to mix and match the powerups, called "perks." The weapons of course are plentiful and customizable.
There's a lot more, I just can't fit it all within the 9 minutes I have to right the review.
Graphics: 9.9
It isn't Gears of War, but it is graphically proficient. You WILL NOT notice any bad textures... unless you really, really, really try. That's all I must say, it looks great, guns are good, the people and absolutely no framerate hiccups EVER. Unless it's that guy with the n00b connection, that's the only time you'd get lag.
Sound:10
Perfect, the sound effects vary from many places and at the same time. And they do a good job showeing how loud something should be compared to something else... Like, if the dog, like I mentioned above jumps on you, and you snap it's neck, it'll be VERY loud, it'll muffle the sound around you, except the sounds that are always loud... like the AK-47 firing 3 feet from you.
Value:9.9
The multiplayer is endless and the single player is easily replayable for fun.
Only 1 problem.... ONLY 1:
The Achievements are only for the singleplayer... but a lot of them are for beating cetain missions on the veteran difficult... which is hard... since 2-3 shots kills you. And it takes you to longer to heal yourself.
Tilt: 10
Because I love it.
Final word:
THIS IS A MUST BUY, PERIOD. I sold halo 3 for it and I don't regret it whatsoever.
