Ubisoft has just issued a press release stating that a new downloadable content pack for Tom Clancy's EndWar on both Xbox 360 and PlayStation 3 will be released December 11th. The Escalation pack will cost 800 Microsoft Points or $9.99 on the PlayStation Network. It includes four new missions taking place on new battlefields which are playable in the game's skirmish mode.
The "Escalation Pack" DLC will include four new exclusive missions on all new battlefields playable in skirmish mode, three exclusive unit upgrades and an extra set of achievements or trophies to expand your experience with Tom Clancy's EndWar. The new missions include the Siege of the Kursk Firebase (Ukraine), the Assault on Devon beach (England), the Raid on Rota naval base (Spain) and the Conquest of Dorsey Knob (USA, West Virginia).

These new challenges will also be available with more fighting power; as the "Escalation Pack" will also introduce three new unit upgrades and 10 new achievements and trophies to unlock.
Also, EndWar will receive a title update on both platforms the same day. This update adds a four versus four play mode.
