Burial Hall/1.03

Swarm
The Burial Hall is a simple building that produces Husks, and then later on, Bone Catapults. You'll probably never be building Bone Catapults, but Husks can be useful, especially since they cost only a small amount of metal which is shared only with Scorpions and Ants. Although building four of these would be ideal to get a full sized mob of Husks in a quick time, you'll mostly be limited to just two because, as well as fighting the enemy, you'll also be fighting for space within your base grounds. Burial Halls are, fortunately, not that big.
