This is the uncharted 2 siege the museum walkthrough. The DLC bring the first co-op add-on game type, Siege, two new multiplayer maps (the museum and highrise), six new skins, and 11 new trophies to make us all look for.
What this new DLC is that makes us capture and hold the territory against waves of difficult AI. Just don't get too nervous whenyou got one to many. The museum is a mixture of rooftops and corridors which should be fun.
