Halo was an extremely good game, and i think it deserved the game of the year award. Halo's biggest asset are it enormous and incredably detailed levels. They feature inside and outdoor enviroments, that are incredibly realistic, with lifelike enviroments, and terrain. The enemies you fight are a bit short in variety, there's only for of them, but there's a lot of them and there AI is really guite good. They will hide behind objects, dodge your gernades, and strike using strategic procedure. You have your own little band of marines, they're actually quite stupid, and are sometimes more trouble than there worth. The things that they yell and say are very entertaining though. The selection of weapons is very nice and detailed, you can choose between an alien or human arsenal, which both have different uses. The human weapons include an assault rifle, pistol, shotgun, sniper rifle, and rocket launcher. Alien weapens are plasma weapons, and are actually more effective and accurate than most human weapons. There are no bosses in this game, which is a nice change, the levels transition in a very fluid motion, and you won't notice the loading. the vehicles were a blast, you can ride a tank or an alien hovercraft. One of the very few faults i can find with halo, was the last half of it or so seemed to much like resident evil. You'll see what i mean when you play the game. You begin to fight enemies that take a bit of the fun a way from the game. The rest i'll leave up to you as a suprise, but i would recomend halo as a good game to anyone
