Zerg race for Enemy Race Manager: High Resolution fork. I simply updated the sprites to higher resolution sprites, slightly modified the unit spawns to try and match Zerg units a little more with the structure they're associated with, and added 3 additional Zerg units. Any other work and coding I 100% attribute to and appreciate the original ERM - Zerg Units modder heyqule: https://mods.factorio.com/mod/erm_zerg
I recommend Krastorio 2 if you want creep to spawn (the purple ground material you see around the Hive in the thumbnail).
Additional Zerg units: Infested Command Centre, Broodlings, and Scourge.
If there are any updates to the base ERM mods or Factorio which require this mod to be updated please let me know.
