Metro: Last Light DLC revealed

Four expansion packs are coming to 4A Games' new shooter Metro: Last Light, publisher Deep Silver announced today. Gamers can grab all add-ons together for $15 via the DLC Season Pass, available now for Xbox 360, PlayStation 3, and PC.

The first expansion for Metro: Last Light is the Faction Pack, which will launch next month for all platforms. It introduces a new and original single-player story that "expands on the Metro: Last Light universe." Further details were not specified.

Following the Faction Pack will be the story-focused Chronicles Pack, as well as the Tower Pack, which will "present a unique solo challenge to Metro veterans." Lastly, the Developer Pack for Metro: Last Light will give players "some interesting tools with which to explore the world of Metro."

"Artyom's story may have been concluded in Metro: Last Light, but there are other characters with stories to tell, some familiar locations that fans of the Metro series wanted to revisit, and some new challenges that 4A wanted to explore," said 4A Games creative director Andrew Prokhorov in a statement. "Since completing the game we have been working on these new stories and hope to release them throughout the summer."

Gamers who purchase the Metro: Last Light DLC Season Pass will also receive a new semi-automatic shotgun rifle called Abzats. Its secondary fire mode shoots six shells in one blast.

Deep Silver did not divulge prices for individual expansions.

PlayStation Plus subscribers can score a 25 percent discount on the Metro: Last Light Season Pass if they purchase it between May 21 and June 4 in the United States and May 22 and June 5 in Europe and the rest of the world.

Metro: Last Light launched earlier this month for Xbox 360, PlayStation 3, and PC. For more, check out GameSpot's review.
