Shacknews has 5 codes for each platform to giveaway. To enter the competition, post a comment on this page. You may only enter for a single platform, so please only comment with the following: PC Entry or PS3 Entry.
If the Shacknews staff cannot tell which platform you are entering for, your comment will not be counted. No purchase is required, but do note that multiple posts won’t increase your chances. Also, be aware that they’re only giving away PC and PS3 versions of the add-on at this time and a copy of Call of Duty: Modern Warfare 2 is required to use it.
Of the five multiplayer maps, three–Carnival, Fuel and Trailer Park–are all new, while the remaining two–Vacant and Strike–are returning from Call of Duty 4: Modern Warfare.
Entries will be taken until tomorrow 12:01pm CST. At that point, winners will be randomly selected and notified via Shacknews message system.
