This is probably the best shooter game that was ever made. A up-side to the game is that it is not to difficult to learn the controlls. So, if you are into those first person shooters, don't pass up this game. Even if you are not into first person shooter, don't pass this game up.

Here is the setting of the story.You play Halo through the eyes of a character known as the Master Chief, an enigmatic cyborg commando whom you don't know much about but whom everyone in the game seems to have heard of and talks about reverentially. Halo takes place in a space-faring future, where Earth's forces have come into conflict with an alien race known as The Covenant. In the beginning of the game, you're awakened out of a cryo sleep and learn that The Covenant are trying to obtain a mysterious artifact--perhaps a weapon--on an artificial ring-shaped world known as Halo, and it's up to you to prevent that from happening.

You quickly discover that you can carry only two weapons at a time in Halo--a realistic touch that many game players assumed for years would detract from first-person shooters but that lends a nice strategic element to this one. This forces you to choose wisely which weapons you pick up from fallen foes and allies and to learn each weapon well. You have to go into each situation knowing that if you, say, up that rocket launcher, you might be able to take out a large unit like a tank with it, but if you don't have a weapon that carries multiple, rapidly fired rounds, you might get overtaken by hordes of oncoming ground troops. Necessity will eventually cause you to realize that the weapons in Halo are very well balanced. Each one has positive and negative traits that might not be apparent at first. The pistol is very basic, but its scope can help you fire on troops who are hiding behind rocks in the distance. The rifle carries many rounds but isn't as effective as energy weapons against foes whose suits possess force fields. The appropriately named needler shoots explosive glass shards that home in on targets, but they often miss their mark if your enemy hides behind an object or runs far enough away. There aren't an enormous number of weapons in the game, but there isn't one that you won't find useful in some way.

Not surprisingly, the computer AI provides the game with an immense amount of replay value. You could play the same section a dozen times--and some are so tough that you'll have to--and not have the same events happen exactly the same way twice. At some points you even have the opportunity to pick from multiple vehicles, such as the Warthog jeep, the Ghost hovercraft, the Scorpion tank, or the Banshee attack craft. You'll have a very different experience depending on which one you choose. If you take the Ghost, you can quickly maneuver around your enemies. If you get in the Banshee, you can rain fire down on them from the sky. If you use the Scorpion tank, up to four marines can hop on the outside. If one of the marines on board has a sniper rifle, he'll start picking off enemies who get too close, while you concentrate on larger targets like cannons and other tanks.

What I am pretty much trying to say is, buy this game if you have the money.
