PC Payday 2 players will get a new free heist mission on Monday called the Charlie Santa mission.

The Charlie Santa heist gives players a custom map where you can either quickly track down two key cards to get into the vault, or, if things go bad, you can drill your way into the vault.

Along with the new map, you also get some new masks (see the friendly fellow above), the chance to unlock a new scope, and there are also some new achievements.
