You can kill from 0 heat if you hit the right spots but it's not always easy. Rook can wreck a Catalyst if you turn sideways so the guns converge properly and aim at his head or the torso XL slot. Goldrush can circle strafe a Catalyst while hitting it's torso with double rocket and large cannon, just enough heat for the kill if you don't miss. Goldrush with that combo can easily kill the other grinders if all of your shots go into the rear cooling fans and their plate. Lmao 2 railgun to oneshot a drill. Goldrushes missing a charge can be destroyed easily if you fire all of your shots into the top plate, just get above them. Catalyst can even kill a dredge from the front if he's a retard and lets you use hammer as a shotgun.

Everything this anon >>327337371 says is how the game has been for me too. I felt like I was doing nothing for a while too but eventually it came together.
