According to a rumor reported in today's Gaming Update on X-Play, the Pandemic forum boards are lighting up with information about supposed DLC for Mercenaries 2. Seems that this rumor centers around the idea that presidential candidates will be available for play in the game sometime in November.
X-Play has attempted to reach Pandemic to respond to the rumors, but they will not comment. Still, we're hoping the rumors are true. Who could be more mercenary than a political candidate?
