Swarm Host Evolution Mission
Start off by killing the terrans.
Continue forward and you will find a locust nest. Destroy it.
After doing so, your swarm hosts will evolve.
Now your locusts can fly.
Destroy the nuclear silo.
Go to the east and kill the terran forces.
Back your swarm hosts though, since they will target them before the locusts.
After you're done with them, just attack the next nuclear silo.
After destroying it, you will have to move your new swarm hosts north.
Burrow them and start attacking the Ash worm.
After it gets down to 50% health, it will burrow to a new location. Just move your swarm hosts and attack it again.
After you're done with it, your swarm hosts will evolve.
Now they have the ability to teleport to anywhere on the map, as long as there is creep there.
Teleport to the base to the east.
After that, go to the base to the north.
Destroying the enemies should be really easy.
After that, you get to choose a strain. I chose the Creeper strain.
