Infinity Ward has today released a new trailer for Modern Warfare 3 debuting the games Spec-Ops Survival mode.

The Horde-style mode lets players work together to take on waves of increasingly difficult enemies and can be played on any of the games multiplayer maps.

You will be able to upgrade your weapons and equipment after each wave using cash received by killing enemies. In the later waves you will also have access to air support which will see friendly soldiers air lifted in to help you.

Finally there are the suicide dogs, these are the good old Call of Duty attack dogs with a little added surprise in the shape of C4!

If you think you are prepared to take on all of this then you can check out the trailer below.
