One of the 1st console FPS that stand shoulder to shoulder with its PC counterparts. If you have an Xbox, get Halo.
Halo : Combat Evolved for the Xbox, is one of the best, if not greatest console FPS. In Halo you play as a warrior bred for battle against an alien force bent on ending humanity. As you move around the game world, you will see some of the most impresive graphics and enviorment ever seen in a videogame.
Halo's controls are great. You use both stick for aim and movement, the triggers for shooting and grenades, and the face buttons for reloading, jumping and melee attacks.
Halo's sound and amazing music score immerse you in the game world, making the game feel even more epic in scale.
When you are done with Halo's epic story, you can connect some Xbox's for some multiplaer madness on a LAN.
