Lucky owners of shiny new 360' and a certain launch title will be happy to hear that plans are in the works to enhance your multiplayer gameplaying:- Counter-operative mode allows you to play missions from the perspective of the enemies; planned as a free download via Xbox Live Marketplace
- Scenario mode gives you different challenges like "taking out bots with only a certain type of gun." Also a free download.
- Map packs will cost an undisclosed amount of money and will support Scenario mode.
