Word from Pax East is the DLC will take place after the campaign mode. The maps are titled: Runoff, WarGames and Swaplands.

In the wake of the Battle of Demeter, IMC Expeditionary Forces travel deep into Frontier space to recover from their recent defeat. On an uncharted world, the IMC begin construction of a new fleet operations base, using newly acquired water collection and filtration plants to support the new base. When drainage operations reveal ancient ruins and artifacts of an unknown origin in a nearby swamp, Spyglass activates an archaeological team to investigate the site. To maintain battle readiness at the new base, IMC Pilots use simulation pods to train for anticipated Militia raids, based on lessons learned in Angel City and IMC Airbase Sierra.

Only three maps is kind of bullshit but I guess it's better than nothing. “Expedition” is the first of three DLC packs and it will include a new "hashtag" search engine to find like-minded players. There will also be new game modes like a 2 on 2 last Titian standing  and new Titian burn cards.

It will cost $10 and will drop sometime in May. Or if you have the $25 Season Pass you'll be way better off.
