More footage of Modern Warefare 3's Spec Ops Survival

Spec Ops Survival We've seen Call of Duty: Modern Warefare 3's Spec Ops survival way back in E3, but just in case you want more they just released new footage of the mode.

It's definitely similar to horde 2.0 of Gears of War 3 but instead of 4, it's just you and a friend. You go against wave after wave of enemies. Each kill earn you money that you use to get better guns, ammo, defenses, and even air support. Seems like a fun mode  to play to get away from single player and multiplayer for a while. The usual enemies for this mode looks like the common terrorists, attack dogs, and eventually the tough Juggernauts.

Part 1

Part 2

What do you guys think? a good addition? or should they stick to Black Ops' zombie mode instead of spec ops?
