Looking to boost Bigfoot and Now They Fly. I'll be online throughout most of the day. Can help out with any other DLC achievements too. Also I have 2 controllers.
Here are the playlists that have Crimson maps on them:
Harvest: Infinity Slayer, Capture The Flag, Team Objective
Wreckage: Big Team Infinity Slayer, Capture The Flag, Team Objective
Shatter: Big Team Infinity Slayer, Dominion*(apparently Mantis don't spawn in this playlist?)
