Deep Silver today released the ‘Developer Pack’ – the third piece of add-on content for Metro: Last Light and a kit that offers several opportunities to re-design the gameplay of the critically acclaimed first person shooter. It is now available worldwide on Steam and the Xbox Live online entertainment network from Microsoft, and the PlayStation®Network in North America. It will be available on the PlayStation®Network in Europe and the rest of the world tomorrow, September 18th.

There are three main parts to the Developer Pack:

• Players can experiment with every gun and attachment combination in the Shooting Range, and complete unique marksman challenges for each weapon
• The AI Arena allows players to pit customisable squads of human soldiers and mutants against each other, or prove themselves in several challenges
• Lastly, players can explore Metro’s cast of characters, and human and mutant foes, up close in the ‘Metro Museum’

The Developer Pack also includes an original solo mission – The Spider’s Nest – that will truly test the nerves of arachnophobes. Use your wits, your lighter, your torch… and the brand new Flamethrower to escape from a spider infested catacomb…

The Developer Pack costs $3.99 / £3.19 / €3.99, and is the third of four add-on content packs to be included in the Metro: Last Light Season Pass, which at $14.99 / £11.99 / €14.99 offers a discount over buying the packs separately, and also includes an additional exclusive weapon, the Abzats.

The final add-on content release for Metro: Last Light – the ‘Chronicles Pack’ – will arrive later this month and features three original single player missions that cast the player as four of the game’s standout characters – Pavel, Khan & Ulman, and Anna – and explore their side-stories away from Artyom’s adventure
