It follows the Retro Map Pack. The first is Junkyard and it’s a Guerrilla Warfare game type, and the second is Stahl Arms and it’s a Warzone. Video is up.
Here’s the official details for the Steel Rain DLC:
MP-09 JUNKYARD
Game Type: Guerrilla Warfare (16 players)
Description:
The junkyards of Helghan are a wasteland to some, but a valuable resource to others. In the main junk processing facility of Helghan, ISA and Helghast Forces are clashing in an attempt to salvage vehicles and supplies for their war effort. Jetpacks are the key to taking the high ground, but the huge Exoskeletons can quickly turn the tide of the battle on the ground.
MP-10 STAHL ARMS
Game Type: Warzone (24 Players)
Description:
As the Helghast write a new and appalling chapter on humanoid experimentation, beleaguered ISA Forces mount a desperate attack on the notorious Stahl Arms research facility, where they hope to free ISA soldiers who have been taken captive. Stahl’s Helghast forces will stop at nothing to ensure that the ISA attack fails, even if it means exterminating the very prisoners they need for their weapons research.
