Hey. This is a simple adaptation of the original swarm mod for version 17. Not mine. Thank you Likos for adapting and Supercheese for creating it
Description
Beware the swarm! This mod makes larger biters, spitters, and spawners spawn multiple smaller enemies on death. Now, for instance, killing a medium biter means you have to deal with the small biters that spawn from the medium corpse.
