Heres how I did it in ONE match. Yes, one.
Bot game, hunter comp doesn’t matter much, I just left them at default T1.
Map: Orbital Drill.
Monster has favor, high wildlife, infinite strikes, 5 second reinforce.
3 points in vortex. CD reduction Perk
Armor up quickly, then head towards the shore until you get to the Two towers that have a bridge between them. Just sit on that bridge, and the hunters will try to jetpack up to you on one of three routes, either up the sides of the towers, or over the lake towards the middle of the bridge (best one). Just vortex on CD, because the wide open spaces will push them far enough that it will be up again by the time they get back to you. I got all 6 hunters (colonists count) in a single vortex a couple of times, goes rather quick, and when your armor gets low, just run and armor up, repeat.
