If you're a fan of 4A Games' vision of post-apocalyptic Russia, you'll have the opportunity to return to the Metro this summer. Deep Silver has announced the upcoming release of DLC for Metro: Last Light.

A season pass is available now, which gives players an early opportunity to put money down the four different DLC pieces rolling out this summer. The Faction Pack and Chronicles Pack are new single-player expansions, the Tower Pack appears to be a challenge mission, and the Developer Pack enables unspecified exploration tools. The season pass also awards a new shotgun that can unleash six shells at once.

The Metro: Last Light season pass can be purchased for $14.99 (1200 Microsoft points) on Xbox Live, PlayStation Network, or Steam. PlayStation Plus subscribers can save 25 percent through June 4. The first DLC, the Faction Pack, arrives next month.
