Dr. Victor Gideon is the true final boss of Resident Evil Requiem, and the toughest fight in the entire game. This complete guide walks you through both phases of the fight, exact attack patterns, weapon priorities, and Insanity difficulty tips — including a no-damage strategy that pro players use.
Victor Gideon is the director of the Rhodes Hill Chronic Care Center and the antagonist who has been pulling strings throughout the entire campaign. Once Leon releases Elpis at the ARK terminal — which doubles as a cure for the T-Virus — Victor abandons his humanity entirely. He replaces his left arm with a massive mutated tentacle and takes one last stand at the bottom of the ARK Facility.
This is a true two-phase final boss. Phase 1 is a controlled melee fight against a humanoid Victor with a tentacle arm. Phase 2 transforms him into a full Nemesis-clone with glowing red pustules across his body, sweeping arm attacks, and a tense QTE finisher.
| Location | ARK Facility — final chamber |
| Playable as | Leon S. Kennedy |
| Required ending | Release Elpis (canon ending) |
| Phases | 2 (Mutated human → Nemesis form) |
| Difficulty rating | ★★★★ Brutal — hardest fight in the game |
| Recommended weapons | Mortal Edge Hatchet, Requiem Revolver, MSBG 500 W870 Police shotgun |
If you have been hoarding Requiem Revolver rounds, stacked grenades, and heavy medical injectors for the last ten hours, this is exactly where you burn them all. Victor Gideon is the last fight in the game — there is no reason to save resources past this point.
Before entering the boss arena, do the following:
After the platform collapses and Leon lands at the bottom of the ARK, Victor attacks in his humanoid form. He has a mutated tentacle arm, decent movement speed, and a tight arena filled with scrap metal piles that double as both cover and obstacles.
Victor's tentacle arm gives him four primary melee attacks in this phase:
Every single one of these attacks is heavily telegraphed. You will see the wind-up frame clearly. Use the Mortal Edge Hatchet to parry, then immediately follow up with shots from the Requiem Revolver or W870 Police shotgun.
Periodically, Victor will leap onto one of the large scrap metal piles at the edge of the arena and begin channeling raw electricity. You will see a bright glowing line appear on the ground indicating the exact blast zone.
You have two choices when this happens:
After the electric blast, Victor lands in a "superhero pose" and stays motionless for about 2 full seconds. This is your biggest damage window of Phase 1. Empty Requiem rounds into his head while he is recovering.
After the cutscene, Victor transforms into a full Nemesis-clone — a massive, pulsating monstrosity with glowing red pustules across his head, arms, and body. This phase functions almost identically to the Plant 43 boss fight earlier in the game, just with more weak points and harder-hitting attacks.
This phase is built around destroying glowing weak points in waves:
Victor only has a few attacks in this phase, all of which can be parried with the Mortal Edge Hatchet:
Strafe left and right between attack waves. Standing still gets you flattened.
Save Requiem Bullets for the head pustules. Grenades for clusters. W870 Police shotgun for the core.
After you destroy enough waves of pustules, Victor will grab Leon with one of his arms. Don't panic — this is meant to happen. A series of button prompts will appear on screen. Tap the indicated buttons (default: square/X repeatedly, then triangle/Y) to escape.
Successfully completing the QTE triggers the final cinematic kill sequence. Leon delivers a Hatchet finisher to Victor's exposed core, the screen cuts to black, the facility crumbles, and you have officially survived Resident Evil Requiem.
The Victor Gideon fight on Insanity is brutal but not unfair. The same mechanics apply, but with these key differences:
For Insanity runs, the optimal strategy is to use Infinite Ammo on the Requiem Revolver (purchased from Special Content Store post-game). This trivializes the pustule destruction phase and lets you focus purely on dodging.
Pro players have completed this fight without taking a single hit on Standard difficulty. Here is the boiled-down approach:
Defeating Victor Gideon completes the main story and unlocks several things at once:
If this was your first playthrough, your next move should be a New Game+ run on Insanity using carry-over weapons and Infinite Requiem. With Infinite Ammo equipped, the entire game can be cleared in under 4 hours, unlocking the Speedrunner and Remarkable Agent trophies in a single run.
Yes, but the default Hatchet's parry window is very tight, and on Insanity difficulty it becomes unreliable. If you skipped The Commander fight (where Mortal Edge is rewarded), go back and complete it before attempting Victor Gideon — the upgrade pays for itself in the first 30 seconds.
No, Infinite Ammo is not required. However, on Insanity the pustule HP is roughly doubled and one mistimed dodge can be a one-shot kill, so equipping Infinite Ammo on the Requiem Revolver (purchased from the Special Content Store after first clear) makes it significantly easier by letting you focus purely on dodging.
No. Infinite Ammo, the Infinite RPG, and all other Special Content Store unlocks do not disable trophies in Resident Evil: Requiem. They are safe to use even on Insanity difficulty runs.
Around 12–18 minutes on Standard difficulty for first-time attempts, and 20–30 minutes on Insanity. Speedrunners using Infinite Requiem clear both phases in roughly 4–5 minutes.
Mortal Edge Hatchet for parry-counters, Requiem Revolver for head shots and weak-point destruction, MSBG 500 W870 Police shotgun for close-range core damage in Phase 2, and at least 2 Hand Grenades for clustered pustule waves and ground orb clusters during the collapse phase.
Yes — failing the button prompts kills Leon and forces a restart of Phase 2. Default mapping is square/X repeatedly followed by triangle/Y. The button prompts are the same family used throughout the campaign, so practice them in earlier QTE moments to build muscle memory.
