Halo is a first person shooter made my Microsoft. It was the first game to come out with the Xbox and its the best...until Halo 2 gets out. The graphics are great and the multiplayer is awesome. You basically fight alien creatures on another planet, but thankfully you get support. Some missions you're by yourself and on others you have a squad with you. You can even play the missions two player simultaneously. If you get an xbox, you need this game.im plannin on gettin an xbox soon and ive heard a lot of good things about halo. could someone explain to me wat its about?
