Deep Silver announces the Tower Pack DLC for Metro: Last Light will be released on September 3rd for Windows, Xbox 360, and PlayStation 3 (the European edition for PS3 is due the next day). Here's word:

The Tower Pack represents a fearsome challenge for every Metro fan. Players have to fight their way up through a heavily guarded tower, a virtual combat simulator. Each level is increasingly difficult – packed with hordes of enemies, mutants and other deadly threats. The best players in this combat simulator will need to master Metro’s unique, hand-made weaponry and deep combat mechanics in order to reach the top of the global leaderboards.

The Tower Pack will cost just $4.99 / £3.99 / €4.99, and is the second 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.
