Multiplayer is great- the gameplay is great, the only thing wrong with it is the killcams are kinda glitchy with the red reticule from killing. You have to install the multiplayer just to play it because it's graphics and detail.
Graphics- Best graphics out right now a realistic as it gets without getting rid of the futuristic feel of halo.
Detail- The detail is so amazing in the game and the maps are highly detailed.
Maps- The maps except Ragnorak are all completely new ideas and non recycled. Ragnorak is Valhalla from Halo 3.
Game- The game feels like halo. They didn't get rid of that halo feel even though a bunch of people are saying it's turning out like CoD.

Overall I give this game a 9.0 (because of the bugs) and I definitely would recommend this game.

I do not personally like the multiplayer but I was never into Halo but the campaign was so amazing.

it's being related to cod because of the default layout, which i didn't realize because i switched to bumper jumper before i did anything. Also there are things called ordanence drops which is like a kill streak in cod, once you get a certain amount of kills you get 3 options which are at random.. Personally after starting with Halo 2 and then Halo 3 being effing bomb, I'd give Halo 4 a 6.9 at the highest. I'm still going back to playing Halo 3. Halo 4 is kinda like MW3, they made it noob friendly and far to easy to kill.
