Today during a PAX East panel, Respawn Entertainment officially announced that Titanfall's first expansion pack is called Expedition. The DLC will arrive in May, presumably for Xbox One, Xbox 360, and PC.
The maps are called Swampland, Runoff, and Wargames. The DLC is included with the $25 Titanfall DLC pass, though it's not clear what it will cost as a standalone download. Two other map pack expansions are coming to Titanfall, though Respawn hasn't said when they will be delivered.
Respawn also confirmed today at PAX East that a new 2v2 Last Titan Standing mode is coming to the game as a free update sometime in the future. There will also be new Burn Cards, the developer said.
The developer also revealed a new "hashtag" system for Titanfall, through which players with similar interests can play together. It's unclear how this will work and we plan to follow up with Respawn to get clarity on the matter.
Finally, Respawn teased that customization options and competitive player rankings could come to Titanfall one day. Daily challenges and special tweaks for existing game modes might also appear in the game eventually, the developer said.
Panel host Geoff Keighley, who spent three weeks at Respawn working on a feature, also revealed that the studio prototyped a single-player mode for Titanfall. Unfortunately, no further details or images of this mode were revealed today during the panel.
