This build has 3 main power spikes. POWER SPIKE #1 is when you pickup 'Tesla Bullets'. It accelerates your trooper wave clear faster than any other item followed by jungle camps 2nd. 3rd is breakable boxes for souls. REMEMBER, troopers are ALWAYS way more souls than jungle. POWER SPIKE #2 is when you get 'Hollow Point' and 'Bullet Resist Shredder'. Both these items combined gives us and our team a multiplier on gun damages since we shred -24% of their bullet resists combined with Mcginnis' high base bullet damage. Walkers will die in seconds after losing immunity so find a small hole or room to shoot the walker from another angle. POWER SPIKE #3 is after you get 'Vampiric Burst' which gives us EVERYTHING from ammo to bullet resist and the power to 1v1 or 1v2 anybody or take any objectives reliably. After this point, you can freely make Fleetfoot and Heroic Aura for mobility and bullet resist followed by 'Spirit Resilience' to fix spirit res.
