>HELLDIVER, ITS TIME WE GATHER MORE SPECIAL OIL FROM THE BUGS. WHO CARES IF WE ARE EATING SHIT, WHO CARES IF WE LOST SEVERAL PLANETS OF IMPORTANCE TO US, AND WHO CARES THAT WE LOST A FACTORY HUB AND THE XENOENTOMOLOGY CENTER, YOU GOTTA PICK UP ROCKS FROM A LITERAL PLANET OF BUGS
A bit on the nose, no?

What enemy surges would (You) like to see?
I'd prefer more Troopers or more Warriors.
Replacing all the scavenger or pouncer spawns with Warriors. More Warriors. Just more things to shoot.
Troopers, because having 30-50 MG raiders fire at you is actually something to be concerned about, compared to the 3 devastators that die to 2 headshots

What's your goal?
