Shotgunning in this game usually means you're the one taking point for your team being the most exposed and forward individual. Due to this reason you'll want to have high damage per second to take things out before they can touch you. Your base card is Shredder as each pellet counts as a stack towards maxing it out providing your team a 60% damage increase to the target you call out (15% per cleaner). Shell carrier is a solid increase of damage and ammunition as you chew through that on most shotguns. And truth be told since you're not fully automatic, and often time rely solely on reload speed as the reason you can't DPS more consistently, Scattergun Skills and Mag Coupler is a must to solve your DPS inconsistencies. Buckshot bruiser for some temp health, only reason you don't pick it up prior to this is because you start a level full health and need damage to be useful. Now 4th level though you can consider grabbing it to increase your survivability. Run Like Hell and Mad Dash offers you one thing, repositioning options. Nothing in this game is more valuable then the option to avoid damage of tallboys, crushers, exploders, or reeker calling hoards if they die while near you. Few movement cards does not make this a "Speedrun deck". Round out the build with damage reduction, more temp health, little bit of weakspot damage and Medical Expert. This card is heavily undervalued because you're trained the doctor is suppose to heal you. But if you're carrying pills, this offers you 15% more on those pills additionally it offers you 15% movement speed for 15 seconds which stacks with Run Like Hell and Mad Dash to clutch up where you should be using pills. Pills are not made to be used in between hoards or while walking along the street. Let your doctor heal you up and save your Pills for moments where you need to kite hoards, reposition away from mutations and hopefully push towards success.
