Of those five 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.
Priced at 1200 Microsoft Points / $15--a price that Infinity Ward owner Activision says "has still provided a fantastic value to gamers"--the "Resurgence Pack" is due on PC and PlayStation 3 at a later unspecified date. For reference, the game's first downloadable add-on hit Xbox 360 on March 30 then followed in PC and PlayStation 3 form on May 4.
Fantastic value? More like thanks for lining our pockets even more...
