WRATH: Aeon of Ruin, another popular retro-FPS throwback from KillPixel and 3D Realms now finally has a release date of February 25, 2021. Currently in Early Access, they also just recently release a second big content update.
It's not currently officially supported on Linux, however it will be releasing properly for Linux next year too. Although from what we've been told it might not be at the exact same time as the Windows version. Until then though, you can actually play it with open source as KillPixel use a modified version of the DarkPlaces Quake game engine which you can find right now on GitHub. Our contributor, Samsai, actually did this and took a look in a previous article and video where it runs well.
The new update that's now available adds in a new level, a new enemy, a new weapon, a new item, a cumulative damage system to enemy pain states, an option for screen flash when picking up items, refresh rate configuration, and options for Always Run / Toggle Run. You can see the update trailer below:
