THQ has announced the first downloadable content pack for Metro 2033, called the Ranger Pack.

The DLC will include two new weapons, the Heavy Automatic Shotgun and the Volt Driver, “Miller’s signature gun.”

Players will also be able to play a new mode, called “Ranger mode.” In it, ammo is decreased but weapons do more damage. As if that weren’t stymieing enough for dedicated players, there’s also a “hardcore” Ranger mode that does away with the game’s user interface.

Additionally, there are new achievements to be earned, worth 250 gamer points on Xbox LIVE.

The back hasn’t received a street date yet.

We were very pleasantly surprised by Metro 2033. You can read our review here.
