For those of you that pre-ordered Uncharted 2: Among Thieves, you now have access to an exclusive beta of the game which features a few multiplayer modes. Among those modes is the new co-op mode called Gold Rush. The goal of this mode is to steal a treasure and bring it to a capture point, all the while avoiding waves of enemies. Each successive capture increases the difficulty and number of enemies. Like other survival and Horde type mode, we found this to be quite entertaining.
