Activision has released details on the last batches of extra content for last year's best-selling Call of Duty: Modern Warfare 3.
Two more Content Collections will be released in August and September. Each will be made available on Xbox 360 first, with PS3 and PC versions following a few weeks later.
MW3 Collection #3: Chaos Pack will go live on August 9th and adds a brand new Chaos Mode to the multiplayer. This setting challenges players to survive against waves of enemies while chaining kills together in arenas with a wide variety of power-ups available.
The Chaos Pack will also include three new Face Off maps and four Spec Ops missions: Vertigo, Arctic Recon, Light 'Em Up and Special Delivery.
Finally, MW3 Collection #4: Final Assault arrives on September 9th and is designed for the most dedicated multiplayer fans. It features five new multiplayer maps, including an abandoned mining town, oilrigs, ocean liners, war-torn New Orleans and the beach of Jersey Shore.
Both packs will cost 1200 Microsoft point. Each map, mode and Spec Ops mission will be made available individually to Call of Duty Elite premium members before the Content Collections are released.
