Rush 1.5base Swarmhost Nydus
into 2.5base Muta for finisher
Spines when build Lair, Spores before swarmhost complete
if you can pay 3 swarmhost, you want to already attack
then you get 5 swarmhost and a 2nd Worm
then you get 12swarmhost meanwhile researching muta
then you build 10till15 muta before you attack with muta
for 4vs4, not even need muta, just 200 supply of swarmhost, 1-2base
A swarmhost is more cost effective as a drone collecting mineral to sent roach/zerglings
Quote
200coins per 1min of locust production per 1swarmhost /// So a swarmhost urns it costs back 53sec in combat
a larve cost 19to33gold depending on uptime of larve production
