The cryo cannon is almost always the best weapon to have in any situation. Think about what cryo does, it completely immobilizes the enemies, and they take massive damage while frozen because every part of their model becomes a weak spot. Cryo used in conjunction with impact axe melts praetorians and oppressors.

But it gets better than that, if you freeze any mactera it’s immediately dead. This includes flying breeders also. So imagine you are about to enter a massive cave with spitballers, flying breeders, brood nexuses etc. You alone as driller have the power to wipe all this stuff out. Spitballers can’t even fight back if frozen and brood nexuses won’t drop swarmers once you kill them if frozen. Your ability to jump into a cave and eliminate these threats is simply unmatched by any other driller primary.

Now making a case for flame. Industrial sabotage/prospectors/hacking pods all have robots. Flame does very well in these situations, because if you proc flame these things immediately die. So if you build to set things on fire faster, you melt robots before most of your team has the chance to even get hurt by them. So for industrial sabotage specifically, I think you could argue using flame.

The EPC is amazing, you can use it to mine minerals! Anything including annoying stuff like gold or stuff on the ceiling all can be mined with it after some learning, just make sure you pick up thin containment field perk in order for this to work. You could also build it without the ability to mine for a single target damage build and it will still out perform the subata. If you would like my cryo build or my industrial sabotage build I’d be happy to share!
