Borderlands 4 How to Unlock the Legendary Oscar Mike Assault Rifle

Oscar Mike is an Assault Rifle that can come in both Cryo or Kinetic forms. At a baseline, it deals an extra +50% Bonus Damage with the first half of its Magazine.

However, what makes it truly exciting is its under-barrel Space Laser effect, which deals a massive amount of damage within the designated radius.

Unlock Location:

• Progress into Carcadia Burns region.
• Complete the Fault Finding side quest.
• Doing so unlocks Genone, the boss that drops Oscar Mike.

Farm Method:

• Defeat Genone after completing the quest.
• Return to his arena via the map if you’ve already killed him once.
• Use the Encore Machine to respawn him for repeated farming.
• Farm until Oscar Mike drops.
