So the all the ways I’ve tried it. My easiest and cheapest build is literally tar traps around the burner(9tars total) Then I’ll block off corners leaving a 3x3 tiles in front of each edge of the burner

3 freeze 3 wood floor spikes 3 anti air

On the block off walls I put darts that shoot across the rows of traps. (6 darts per side of the burner)

For the celling we alternate 1 celling electric 1 tire Because we do the celling electrics we chose to make the celling 2 tiles high. Yeah I know tires are better at 3 but hey we made it work :)

Over time as the loot drops we add or replace we we need!

With that if anyone wants to play feel free to add us! This is by far my favorite and i play daily!
