Additional content
This content requires the base game Call of Duty®: Modern Warfare® 3 on Steam in order to play.


Redeploying with an arsenal of content unlike any in franchise history, Call of Duty®: Modern Warfare® 3's first downloadable “Collection” arrives stockpiled with not only four Multiplayer / Survival Mode Maps, but two Special Ops Missions — the first time Call of Duty ® has ever made Special Ops downloadable online.

Armed with just this one content pack, players can choose between heading to a militarized Central Park in Liberation, destroying scenic vistas in a seaside Italian getaway in Piazza, raining glass on New York passersby from 70-stories-up in Overwatch, and battling beside a downed Air Force One in Black Box.

As if that breadth of multiplayer variety wasn’t enough, fans of Special Ops can hop aboard snowmobiles to infiltrate a diamond mine in Black Ice or head to India, where Negotiator will leave the fate of hostages in their hands.

I would really appreciate the feedback after the purchase.
