Releasing these screenshots, Deep Silver unveiled that Developer Pack, the third DLC (downloadable content) for Metro: Last Light, will be available worldwide on Steam and Xbox Live on September 17th, and will hit the PlayStation Network on September 17th in North America and September 18th in Europe and the rest of the world.
With this DLC, 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 will cost just $3.99 / 3.19 / 3.99, and is the third of four add-on 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.
