The Stimulus Package is now available for all three formats: Xbox 360 (Xbox LIVE), PlayStation 3 (PSN) and PC (Steam). The DLC was an Xbox 360 exclusive for 30 days, but during that time Infinity Ward's first map pack had over 1 million downloads within 24 hours of its release. Within a week the DLC was downloaded over 2,5 million times! The Stimulus Package consists of five multiplayer maps - three totally new ones and two brought back from Call of Duty 4. It's likely that some remakes might end up in the advanced warfare multiplayer maps list sometime in 2015.
If you play Modern Warfare 2 regularly the Stimulus Package is totally worth the price, as the maps offer quite a bit of variety. Ghosts, the latest COD game, features Call of Duty: Ghosts Killstreaks from MW2 and has a few remakes in store for long time fans.
