Activision have released two new videos showing the Modern Warfare 3 Spec Ops Survival mode.
Gamespot were able to get hold of the trailers during the Call of Duty XP event in Los Angeles.
This release comes a week after Battlefield 3's beta was released, which enabled players to partake in the Operation Metro multiplayer mode, the limitations of which caused unrest amongst Battlefield's hardcore gamers, and a withering criticism from DICE's community manager Daniel Matros.
Activision will be hoping for more success when their demo goes live in the next few weeks.
Modern Warfare 3 is released on XBox 360, PS3 and PC on November 8.
