Titanfall "Frontier's Edge," which seems fitting given that the included maps drop players into wildly disparate parts of the universe.
Dig Site sees squishy humans and giant, stomping mechs throw down in the wreckage of an abandoned mining site. Export likewise sees combat in a mining facility, though this one happens to be located on the side of a mountain instead of a rocky pit. Finally, Haven offers players an excursion to a relaxing beach resort, where they're free to shoot one another in peace and tranquility.
Respawn has yet to reveal a release date for Frontier's Edge, though we do know the DLC will feature a $10 price tag on debut. Unless, of course, you've purchased the $25 Titanfall Season Pass which includes Frontier's Edge and two other content packs at a slight discount.
