How to Beat Genone

Genone isn't a pushover, and if you come unprepared, you'll burn through lives and ammo quickly. Here's what you should know before engaging:

Frag Grenades: Alongside regular bullets, the Oscar Mike can fire grenades that deal heavy Incendiary damage. These are especially lethal against Flesh-type enemies, and they also leave behind fire hazards that control the battlefield.

Laser Charge Attack: The second trait allows you to charge up and unleash a massive laser beam. While charging, you'll see an AoE marker on the ground that indicates where the blast will land.
