Chimney vent
Infobox:Chimney Vent
Space Age expansion exclusive feature.
Chimney Vents are part of the natural terrain generation on Vulcanus, typically found nearby sulfuric acid geysers. They act as obstacles to the player's factory, and movement, similarly to rocks.
Chimney vents come in five varieties - Extinct chimney vent, faded chimney vent, chimney vent, short chimney, and truncated chimney. The first three varieties can be mined for Sulfur and Stone, whilst the latter two only yield stone.
