Updated on February 28, 2026 by Jessica Orr: Lucas is the final boss of the Not a Hero DLC for Resident Evil 7, and he’s a pretty formidable opponent no matter what difficulty you’re playing on. There are a few tricks you need to implement in order to kill the unhinged Baker son for good. We’ve updated this page with more pictures and some extra tips to help you take down Lucas as quickly and easily as possible.

How to Defeat Lucas in Resident Evil 7 (Prep)

Before the fight, you need to proceed through the halls to find a locked door requiring power. Lucas can be seen through some glass windows working frantically at a computer. Head through the door on the left at the end of the hall to find the power switch. Returning to the hall, Lucas will spot Chris and dash out of the room. Follow him through the locked door once it finishes powering up.

The hallway behind the power-locked door will be guarded by a turret. Turn quickly to the left and enter the room Lucas was previously in to find some incendiary grenades and a lock pick. You’ll also have the opportunity to save and use the item box one last time before the final fight with Lucas.

Once ready, head back to the hallway towards the turret. If you duck to the left at the curtain before the turret, a locker can be opened to find some shotgun shells. Zip past the turret and through the door at the end of the hall. After a brief conversation, Lucas will attack Chris from behind and push him to the ground, causing Chris to shoot Lucas in the head. Lucas will then mutate into a three-headed behemoth and the showdown will begin.

You’ll have a few moments before the fight begins to break open the many crates scattered around the room and grab the anti-regeneration (RAMROD) rounds from the shelf of the machine in the middle of the room. This time should be used as efficiently as possible, as the mutated Lucas is incredibly aggressive and has a jumping lunge attack he can use to close distance, making looting during the fight very risky.

Once the fight is in full swing, you’ll want to concentrate fire on Lucas’s head or the weak spot on his chest to deal maximum damage. Using RAMROD ammo will stagger Lucas, similar to the big White Molded boss fight, exposing the red weak spot on his chest for follow-up damage with a regular weapon (the shotgun is best here.)

About halfway through the fight, Lucas will retreat momentarily to the top of the machine in the center area (right above where the box of RAMROD ammo is located) and begin releasing spores into the room. Even with the upgraded respirator, Chris’s oxygen levels will begin to fall. Lucas returns to his onslaught, now even more aggressive and capable of jumping over the machine to attack.

Continue damaging and evading Lucas while taking notice of the green flashing lights on the walls. These lights indicate oxygen stations that you can use to restore your breathing capabilities when oxygen levels fall critically low. The oxygen stations cannot be used while reloading or healing, and improper timing can give Lucas the opportunity to lunge in and unleash significant amounts of damage.

Stay out of reach and keep the focus on Lucas’s weak spot until he staggers and begins to melt. The final cutscene will begin and Chris will finish Lucas and his sick game for good.
