Years ago, back in 2022 there were facepunch commits of a volcanic biome (hackweek-caldera), which unfortunately never made it into the game files. I was interested in this idea before, but have further got inspired by those commits and have since been planning for this volcanic themed map, resulting in the following:
         CALDERA RIFT TRAILER

• It started with violent earthquakes. The ground cracked open, volcanoes erupted, tearing through buildings and burying towns in ash. Cities collapsed in chaos. Those who made it out alive grabbed what they could and scattered across the map, forming camps, building shelters & fighting to survive. Out here, it’s every survivor for himself. No mercy. Just fire, ash… and the will to outlast the rest.
