My Sniper/DPS deck with the cards I've unlocked after a recruit level run through. This is aimed at completing veteran difficulty with 3 strategies.
First, it prioritizes a few powerful team cards necessary for higher difficulties, like Inspiring Sacrifice and Money Grubbers.
Second, it provides you with early damage options with the Two is One One is None and Admin Reloads combo. You never have to manually reload, simply swap between your sniper in your primary and your weapon of choice in the secondary. I like to equip an AR in my secondary and rapid swap between sniping mutes from a distance and clearing out the common infected that have piled up. Combined with shooting gloves, this combo is even more broken. This portion of the deck can apply to any high dps build, I just like how it combos with my Sniper playstyle.
Third, it maximizes bullet and weakspot damage so you 2 shot mutes.
