1. Cost: 9/10
2. New Features: 8/10
-Spartan Ops: This game mode is a nice breath of fresh air for the Halo series, because it plays out like the "Special Ops" game type in MW2. One cool thing is that you can use your loadouts in multiplayer in Spartan Ops. Although it is lots of fun, I found that this particular addition to the game was getting quite repetitive after a while, and requires xbox live gold even to play single player.
-Promethians: The new alien types in Halo 4 are quite creative, including one that flies and protects others with force fields and catches grenades, and one that can crawl along the ground, walls, and ceilings. The new Promethian guns are pretty awesome and use beams of light to do damage. The new weapons include the Binary Rifle, a sniper rifle, a LightRifle, which is a carbine type gun, the Suppressor, an assault rifle, and the Boltshot, a pistol.
-Forge: Forge mode is a mode where players can make their own maps by adding items and changing landscapes to fit their liking. Everything is the same as Halo Reach and Halo 3, except that you now have to have an xbox live gold membership to use it.
-Game Modes: Halo 4 has a wide assortment of game modes, most of which are typical for first person shooters. Some of them are Infinity Slayer (Team Deathmatch in COD), Free for All, and King of the Hill. The Flood game mode returns from Halo Reach, same as always. 343 Industries is constantly adding new temporary game modes to the game, like a football type game mode when the super bowl happens, for example.
Campaign: 9/10 I found the story to be quite good compared to most of the Call of Duty games. Luckily, 343 Industries knows that making the story revolve around the Master Chief, even if he is totally awesome, would not be very interesting. Instead, the storyline focuses on Cortana, the master chief's AI companion, and her rampancy (I think when an AI overthinks and burns themselves out). The special effects in the campaign are incredible, like when a spaceship explodes in a satisfying purple cloud , or even simply when a grenade blows up!
Conclusion: Halo 4 is an amazing game with excellent gameplay, breathtaking graphics, and a good multiplayer unlock system (yes, we're talking to you, Halo Reach!). The game is totally awesome, so if you are reading this and you own an xbox 360, then go out and buy it!
