Hey below are the patch notes for 1.2 which adds some new stuff!.
Added horde mode gamemode which can be accessed from the main menu. Players will now be able to select between "Horde and Rogue" modes Rogue refers to the initial roguelike gamemode the game launched with.
Two horde mode maps. "Warehouse" and "Sewer" upon selecting the game mode one of the two maps will randomly be selected (I've put some screenshots below).
A couple new music tracks which can play during Claw, Rogue, and Horde levels.
Support for volumetric lighting effects.
A few bugs lol.
