General information[]
The Under Hall is one of the first buildings you obtain after defeating Moloch upon the descent into the Inferno Cavern. Upgrade harvesters and Resource Pods quickly so you can upgrade the Under Hall.
This building is the Inferno equivalent of the Town Hall. The only major difference is that it takes more space (the Under Hall is 8x8 blocks, while Town Hall is 6.5 x 6.5 blocks).
