THQ has announced that Metro: Last Light's Limited Edition will include the Ranger Mode difficulty setting.
Ranger Mode is a game type made to make Metro: Last Light harder. In addition to that, the LE will also include the Ranger load-out, which contains "bonus military grade bullets" to spend on weapon upgrades and equipment. Also, you'll get the AKS-74U, a variant of the AK Russian assault rifle line.
In Metro: Last Light's predecessor, Metro 2033, Ranger Mode came in two types: easy and hardcore. On easy, the player would get killed by a few bullets and the crosshairs were disabled. In Ranger Hardcore, the HUD itself was off entirely and the player could get killed by a single bullet.
So, how to get the Limited Edition? It's quite simple, really. Just pre-order or buy the game when it launches. It seems THQ is following EA's footsteps when it comes to "Limited Editions" and are making them available for inital runs of the game.
For now, THQ has made no mention if the mode will be available for download at a later date or if Metro: Last Light will get a Collector's Edtiion.
Metro: Last Light will be out in March 2013 for the PC, Xbox 360 and the PS3.
