It’s this smart AI system that makes for a noticeably unique gameplay feel. Another very nice feature is the seamless transition into vehicular elements. As you venture through mission objectives, a variety of enemy flyers and on-ground buggies are yours for the taking. Come across a vehicle and the camera will pull back to a third-person view as you strap in and motor through crossfire. A co-op mode allows a friend to join you in the single-player missions. For chaotic fighting action, up to four players can duel in split-screen deathmatch mode or link systems for LAN play. However you choose to hero your way through Halo: Combat Evolved, the action should break in your new Xbox in explosive style..
