Gears of War Judgment

Multiplayer:
It was announced at E3 2012 that Gears of War: Judgment will feature a new game mode called OverRun. As the COG, you’ll be protecting two sealed Emergence Holes and a Hammer of Dawn beacon. If you successfully defend the Hammer of Dawn, the round will end, blowing the Locust to smithereens. If the Locust reach the Emergence Holes and uncover them however, the COG are ripped to shreds by a flood of Kryll. Rod Fergusson ‏has also said that Judgment will once again still feature Normal Versus Multiplayer modes.
Epic have also revealed another new Multiplayer Mode called Free-for-all. It is now the second mode to be confirmed along with OverRun. Young Marcus, Young Dom, Anya, Sam, Dizzy, COG Gear and Onyx Guard were also shown to be playable Characters as seen in the Free-For-All Mode Gameplay.
Quinn DelHoyo confirmed that the Locust will not be playable in Versus Multiplayer. He also announced it will be red and blue COG teams.
