Epic Games has announced that Gears of War 3: Raam's Shadow is coming to Xbox Live on December 13. It'll sell for 1200 Microsoft Points ($15.00).
Raam's Shadow is set before the events of the first Gears of War, and will feature a mix of new and obscure characters. Included in the package are six new multiplayer characters, the Chocolate Weapon set and 250 points' worth of Achievements.
"RAAM’s Shadow drops players into the events of Sera post-Emergence Day, as Zeta Squad is enlisted to evacuate Ilima City and protect the citizens against a Locust Kryll storm," goes the story. "Taking on the infamous Locust leader from Gears 1, General RAAM, Zeta is led by Michael Barrick (from Gears comics fame) and comprised of familiar faces such as Lt. Minh Young Kim (Gears 1) and Tai Kaliso (Gears 2), and also includes a new female comrade, Alicia Valera.”
If you bought the $25 Gears Season Pass (it's hard to keep track of all this crap) you will get this without having to buy it.
