Er zijn vijf screenschots verschenen die horen bij de Faction Pack voor Metro: Last Light. Deze DLC is voor de hardcore speler van de game natuurlijk gratis binnen te halen als bezitter van de Season Pass, maar anders kost het je 5 euro of 400 Microsoft Points. Wat je krijgt is onder andere wat nieuwe missies en herinneringen aan waar het begon in Metro 2033.

The 'Faction Pack' includes three original single player missions, each casting the player as a different specialist from the warring Factions. Returning to some classic locations from Metro 2033, these missions feature new weapons, the return of a truly terrifying mutant foe, and offer three distinct gameplay challenges...

As a Special Detachment Sniper of the Redline, players must infiltrate a heavily guarded Reich Outpost at night, under the cover of a deadly radioactive storm...

...before defending the Frontline as a Reich 'Heavy', armed with some of the most devastating weaponry found in the Metro.

Lastly, players take the role of a Polis Ranger in training, tasked with exploring the vast Library complex for artifacts and relics. Salvage can be exchanged for ammunition, filters and hazard suits allowing ever deeper exploration into the Library. Rangers are advised to ignite torches and leave a trail of lights, so they can find their way back to the base before their precious oxygen runs out...
