One of the best first person shooters ever made.
Finally, a shooter with an expansive environment with the permission to roam as you like and find some pretty cool glitches that are fun. The vehicles are very well done and fun to use though in this first one, you can only be the gunner in campaigns, but thats alright. The weapons are all unique in their own way and are not useless for any reason. Very well done 1 player.
Halo 2 had better multiplayer, but Halo still had a fun franchise of online and screen splitting gaming, for most of the maps were well done and don't have to many lousy glitches. The graphics are amazing hands down.
The music is awsome, the sound effects are amazing and not ripped off of other games.
It can be found very cheap now and should not be passed by a shooter gamer, because this is quite possibly the best shooter ever.
