Today’s PSN Store update, aside from the LittleBigSanta costume, includes some great DLC for Ubisoft’s Tom Clancy’s EndWar. Aptly titled, the Escalation Pack brings more excitement to the game with extra missions, upgrades, and trophies; all for a small fee of course. Hit the jump for the full list of what’s included.

4 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) and are all playable in skirmish more. To make matters even more interesting, 3 new upgrades and 10 additional trophies are included. It looks as if the competition just escalated (pun intended).

Ubisoft is also pleased to announce that a free upgrade will be coming as well. This one will allow for four vs. four battles. Now you have no excuse for sitting on the sidelines. The update is scheduled to hit early in 2009.
