RimWorld Players Are Using Wall Lights for Gas Execution

This trick keeps your colony efficient and deadly.


How to Turn RimWorld Wall Lights Into a Lethal Gas Chamber is a simple execution method. You create a sealed room, flood it with toxic gas, and trap enemies inside. Research shows this neutralizes threats without alerting nearby raiders.


Here is how the setup functions. Connect a pipe to a toxic gas source, then seal a small chamber. Place wall lights on the outer wall to disguise the block as normal lighting. Studies indicate players use this method to silently remove prisoners or threats.


One line takeaway: Use sealed rooms and gas pipes to turn decorative wall fixtures into hidden execution chambers.
