Halo may have came late for the PC, but it's still a fun and exciting game.
Halo has a great story to the game other than being just a shooter. You have a variety of guns, vehicles, and gadgets with you in the game like assault rifles, pistols, sniper rifles, tanks, warthogs (jeeps), banshees, grenades, etc. The guns fire well have a nice sound and feel as well as vehicles, grenades go boom everything. In the game you have health, but you also have a shield. It acts as a buffer for your health until you really take damage. What's good about it is that it recharges and it can help you beat a mission without health frustration. The are 10 levels with terrain variety like snow, urban, grasslands, etc. The sound and gameplay is good, but the graphics are kind of outdated.
Halo: Combat Evolved is a great game for the PC and is lots of fun. If your a fan of a shooter than you better go buy this game.
