Check out the new video for the new Metro: Last Light DLC, Faction Pack.

"This add on includes three original single player missions, each casting the player as a different specialist from the warring factions -- the Red Line, the Reich and the Polis Rangers.

To allow fans a first glimpse of the add-on content, Deep Silver also released a trailer for the 'Faction Pack'.

The video shows the three different roles the players can take on: the special detachment sniper of the Red Line, the heavily armed Reich soldier and the Polis Ranger." The DLC is out now worldwide.
