One Weapon Mastery Challenge Haz.2-Deep Rock Galactic Survivor Update3: Masteries-CPSPR Flamethrower

Deep Rock Survivor is a Single Player Rougelike auto-shooter which is what sets it apart from its co-op version. More of a horde battler level based where the goal is to complete the run and return to upgrade to run the next run. Tons of weapons and combos that go along with the upgrades. Its you against all of the planet's Hoxxes. Also, there's a rock in my boot.
