Gears of War 3 marks the final game in this Xbox 360 exclusive trilogy. Players have followed Marcus Fenix from his jail cell beginnings to this final chapter, as the war for Sera has now split three ways: humans versus Locust vs. Lambent. In the third chapter, all bets are off the table as the human government has been disbanded, while the remaining members of humanity fight for their lives; not everyone will survive to see the end of the war. Gears of War 3 packs 8 to 10 hours in its single player mode, with nary a break in the action, producing enough explosions and large scale battles to rival any summer blockbuster movie. For the first time in the series, players will play characters other than Marcus Fenix. In addition, the co-operative online play for the campaign has been expanded from two players to four. Every online multiplayer mode you remember from Gears of War 2 shows up in 3, including the ranking system. Earning experience from defeating your enemies and completing online objectives allows you to increase your rank; with each rank you receive, up to 100 ranks total, new weapon skins and characters are unlocked for multiplayer use. In addition, you can also earn badges, such as killing a set number of enemies with one weapon, to earn these rewards. While all multiplayer modes have seen small additions, one entirely new multiplayer mode has been added: Beast Mode. In Beast mode, you and up to four other online players take on the roles of various Locust enemies in an attempt to defeat the computer controlled human opponents before time is up. As you win more rounds, stronger Locust troops become available, such as the Grinder or Berserker. Gears of War 3 is releasing on September 20th, 2011 and utilizes the Unreal Engine 3.5 engine; as the developer of Gears of War 3, Epic Games, have created this engine, you can be assured that Gears of War 3 looks and runs as good as it plays. For new fans and series veterans alike, Gears of War 3 is a must-play experience on the Xbox 360.
