The Zombie King in 'Resident Evil' is a beast, no doubt, but here's how I tackled him after a few frustrating tries. First, stock up on ammo—especially shotgun shells or grenade rounds. His weak spot is his head, but he moves erratically, so patience is key. I found crouching behind cover and waiting for him to pause before unloading into his skull worked best. If you're low on health, kite him around the arena—there's usually some space to avoid his lunges.
Another thing I noticed is that environmental hazards can help. Some areas have explosive barrels or traps; luring him near those can chunk his health. Don't waste time with pistols unless you're desperate; go for high-damage weapons. And for the love of survival, save your game before the fight. Nothing worse than dying and realizing your last save was an hour ago.
