Titanfall's first map pack, Expedition, will contain a new playground set in a rather muddy swamp, so don't expect your Titans to come out looking clean. According to a new blog post and video below from developer Respawn Entertainment, this map has taken "years to reach its final form."

Known as Swampland, the map went through "years of twists and turns and false starts," said Chris Dionne, the map's designer. Work on a swamp-based map began in the summer of 2011, nearly two years before Respawn officially announced Titanfall. But according to Dionne, progress on the map was shelved for "almost two years," and only picked back up after the studio had completed design work on the main game.

"With Swampland I tried to add a unique experience to Titanfall while staying true to the original themes of the level, like overwhelming nature and its intersection with technology. This was a level born of heavy experimentation and iteration," said Dionne.
