Is this a thing, and have you got video evidence?
Pretty sure mgamerz has a video of that mod. But I am not sure how clearly it shows all factions combating each other. Basically, it was a plat game where you can hack organics too.
I have done a few saboteur solos with this mod, and collector enemies were easily the best enemies to hack. I couldn't do a phantom vs. praetorian because they don't appear in the same wave with the default compositions. But praetorians wreck all humanoid enemies due to their continuous melee-stunlock, and phantoms would get wrecked.
Edit: I've had a single possessed praetorian and/or possessed scion wipe more than half the wave budget (other bosses simply couldn't do that). I can't play for another month or so, else I would've made a video about this.
