Star Wars Battlefront gives you the chance to play as a soldier in intense multiplayer battles with up to 32 people. Choose your allegiance and pick a soldier from one of four different armies. Fight on ten legendary planets and use a variety of weapons and vehicles, including X-wings, snowspeeders and AT-ST's. Keep your wits about you and victory may be within your reach. Experience the chaos of battle as you fight the greatest wars in the Star Wars universe. In addition to the single-player and various multiplayer modes offered in Star Wars Battlefront, a unique "Conquest" mode adds an innovative and strategic gameplay element to the action. After each battle is completed and the planet is conquered, the winning team will be rewarded with a special "bonus" ability that can be deployed in future battles in an attempt to take over the Star Wars galaxy planet-by-planet.
This First/third person shooter in the star wars universe isn't limited to the campaign, you can spend hours battling in fields of your own choice, even conducting galactic campaigns that never really play out the exact same.
The AI is actually acceptable too, many games' AI is horrible, but you can actually lose to this AI. The combat system is fairly balanced aswell, to more Uber-pwn guns, just simple guns that can still be used efficiently. I have had this game for 6 years and I still play it.
