Build a Loadout

Warthog:
T1A cancels out the effects of MPA. In tier two I would usually recommend T2B, but since spread is reduced by your Overclock, there's no need for more damage here. A glyphid can only die once. This allows you to take T2B. T3 is really up to you. I like T3C but T3B works fine too. You won't be spam firing this, so T3A isn't the most useful but you do you. T4B is a must, no discussion. T5A is just the better option with this build. You need the added crowd control
 
Breach Cutter:
HVC makes it so you can take armor break in T4 while also applying electrocution which stuns enemies. This gives you openings on for example Pretorians to do weakpoint damage using Warthog. It does well against Macteras, it erases crowds and it also works against big bois.
 
Grenade:
The large ammo supply on your weapons makes it so you don't need a damaging grenade. Instead, use this to keep Macteras occupied while you shoot their guts, gather crowds in one spot and erase them with one breach cutter shot. You can have it cover your back while mining and make enemies approach you from the direction that is most convenient.
 
The synergy in this build is simply outstanding.
