"Siege" mode is an expansion of the "Survival" game type, in which a team of two or three players must defend a territory and survive against an ever-increasingly difficult set of enemies. In addition to the new mode, two new maps will be added for competitive play: "The Highrise" features a series of destroyed and under-construction buildings, based on the Nepal map from the single player campaign. "The Museum" is based on the tutorial level from the story, featuring a number of secret climbing routes to get a better vantage point.
The add-on will be available on April 22nd on the PlayStation Store. For a list of all the new Trophies, check past the break.
