Oni features a diverse arsenal of ranged weapons, each with unique characteristics. You'll primarily acquire these by picking them up from defeated enemies. Ammunition is scarce, so use firearms judiciously. Here's a breakdown of common types:

- Pistol: Standard sidearm, decent accuracy, low damage. Good for headshots on unarmored foes.
- SMG (Submachine Gun): High rate of fire, low accuracy at range, good for suppressing groups.
- Rifle: High damage, good accuracy, slower rate of fire. Excellent for precision shots.
- Shotgun: Devastating at close range, wide spread. Ineffective from a distance.
- Plasma Rifle: Energy weapon, high damage, often has a charge-up shot.
- Mercury Bow: Fires explosive projectiles, excellent for area damage and armored targets.
- Rocket Launcher: Extremely powerful, slow projectile, limited ammo. Best for heavy vehicles or bosses.
Always prioritize picking up weapons with full magazines, and switch to melee when ammo runs low.
