How to Unlock the Oscar Mike Assault Rifle in Borderlands 4

The Oscar Mike Assault Rifle is one of the most coveted Legendary weapons in Borderlands 4, not just because of its raw firepower but because of its unique dual Legendary effects. Unlike most weapons that typically provide one standout ability, the Oscar Mike offers two devastating traits that make it an essential addition to any Vault Hunter’s arsenal. This rifle blends utility, high damage, and versatility, making it a weapon worth hunting down.

To obtain the Oscar Mike, players must first progress through the Fault Hunting quest. This side mission begins after speaking to Leopold at the Society for Amateur Seismology Enthusiasts. Completing this step unlocks access to the Yawning Yard in Lopside, Carcadia Burn, which is the battleground where you’ll encounter Genone, the primary boss responsible for dropping the rifle. Without advancing this questline, the area remains inaccessible, so this prerequisite cannot be skipped.

Once you make your way into the Yawning Yard, be prepared for an intense combat challenge. The zone is packed with enemy waves and requires careful navigation using geysers to reach elevated platforms. Along the way, players will need to buy Borderlands 4 Cash clear multiple rooms before locating the server chamber. There, the Echo 4 device is required to hack into a console, initiating the final boss fight with Genone.

The battle against Genone is demanding, primarily because he comes equipped with two shield layers that make him highly durable. Using Incendiary weapons is a mistake, as Genone can absorb fire-based attacks. Instead, Shock damage should be prioritized for breaking through his shields, followed by Corrosive damage to cut through his armor. This combination allows you to dismantle his defenses efficiently while keeping the pressure high. High DPS weapons and strong damage-over-time effects are particularly effective in this encounter.

Defeating Genone provides the chance to earn the Oscar Mike Assault Rifle, though Legendary drop rates mean multiple attempts may be necessary. While there are rumors suggesting Sidney Pointy Legs might also drop the weapon, farming Genone remains the most reliable method. Dedicated players should prepare for repeated runs, as the effort is well worth the payoff once the rifle is secured.

What truly sets the Oscar Mike apart are its unique abilities. The first Legendary trait enables the weapon to fire Fragcendiary Grenades through its alternate firing mode. These grenades inflict heavy Incendiary damage against flesh enemies while also creating Fire Hazards, offering strong crowd control in addition to raw output. This feature alone Borderlands 4 Items makes the weapon one of the most versatile tools in a player’s arsenal.

The second major ability is its chargeable laser attack. This move requires a brief charging period, during which an area-of-effect marker appears on the ground, showing where the blast will strike. If timed correctly, this laser can devastate groups of enemies or deliver crushing damage to bosses. Its cooldown balances its immense power, but in strategic hands, it can turn the tide of even the toughest fights.

Adding to its uniqueness, the Oscar Mike also grants a +50% bonus damage effect to the first half of every magazine. This encourages careful ammo management, as reloading frequently allows players to maximize their damage output. When combined with its grenade-launching alt-fire and laser ability, this weapon becomes a tactical powerhouse that rewards smart and aggressive playstyles.

For players seeking a weapon that embodies the chaos and creativity of Borderlands 4, the Oscar Mike Assault Rifle is a must-have. It offers not only overwhelming offensive options but also demands strategy in how it’s used. Securing it may take patience and multiple boss runs, but the results speak for themselves: a weapon capable of carrying you through some of the toughest challenges the game has to offer.
