The first content collection for Modern Warfare 3 has just recently landed on PC, adding new multiplayer maps and a couple of spec ops missions. The second pack will do the same, but also introduce a new 1 vs 1/2 vs 2 mode called Face Off. According to the trailer above, the first two Face Off maps will be released for free to give everyone a taste of how it plays. Two more will then be added in the full content pack later. All of the dates refer to the Xbox version, however. The last DLC pack took more than a month to reach the PC. Expect similar delays again for content pack 2.
