Pre-order Metro: Last Light at retailers worldwide to receive Ranger Mode DLC free of charge, Deep Silver has announced.

Ranger Mode ups the challenge by removing the HUD, providing deadlier combat, and dramatically limiting resources such as ammunition and gas mask filters. In this mode players will be kitted out with exclusive weapon, the Russian AKSU, and an additional 100 military grade rounds.

Pre-order from GAME and you'll receive the Special Pre-Order Edition, which also includes the RPK, a machine gun with a high rate of fire.

Metro: Last Light will be released on May 17 for PC, Xbox 360 and PS3.

THQ announced pretty much the same incentive late last year, before being forced to sell off its assets.
