Insanity Mode — Complete Guide

Insanity is the hardest difficulty in RE9 Requiem — unlocked after first completion. Enemies hit harder, save points require Ink Ribbons, and Victor Gideon's orbital cores regenerate. New Game+ with fully upgraded weapons is strongly recommended.

How to Unlock Insanity
Complete the game once on any difficulty (Casual / Standard / Classic all count).
Insanity appears in the difficulty select screen at the start of a new game or New Game+.
New Game+ (carries weapons, Credits, Antique Coins) is strongly recommended for Insanity.
Buy Infinite Ammo for Requiem Revolver (12 Antique Coins) from the Bonus Content shop BEFORE starting Insanity if not attempting S+ Rank.

What Changes on Insanity

Enemy HP

All enemies have approximately 1.5–2x HP versus Standard difficulty.

Enemy Damage

All enemy attacks deal approximately 2x damage. Standard zombie grab deals ~50% HP on Insanity vs ~25% on Standard.

Save System

Ink Ribbons required to save at typewriters. Each chapter has 3–5 typewriters. Ink Ribbons available from Merchant (1,500 Credits each) and scattered in the environment.

The Girl (Grace)

Significantly faster patrol speed. Alert Mode triggers at 50% closer distance. Flash Grenade stun is reduced to 3 seconds (down from 5).

Victor Gideon Phase 2

Orbital cores regenerate ONCE after being destroyed — each core must be destroyed twice. Second destruction requires Requiem Revolver with Piercing Enhancement (RPG only destroys first time).

Resources

Enemy drops are reduced by approximately 30%. Ammo spawns in the environment are reduced by 20%. Credits from enemies are unchanged.

Bosses

All bosses have additional HP and new attack patterns. The Commander Phase 2 smoke is denser (shorter visibility radius). Titan Spinner Rapid Charge in Phase 2 has a shorter telegraph.

Recommended Insanity Loadout

Primary (Leon) Alligator Snapper
↑ Power MAX -> Magazine Capacity MAX -> Reload Speed Lv.2 -> Exclusive (Hollow Point)

Hollow Point Exclusive converts all rounds to 2x stagger chance. On Insanity, stagger control is critical — standard zombies require 2–3 headshots without Hollow Point vs 1–2 with it.

Shotgun (Leon) W870 Police / MSBG 500
↑ Power Lv.3 -> Choke Lv.2

W870 for crowd control. MSBG 500 for boss cysts (Chunk, Titan Spinner). Do not max both — choose MSBG 500 for the boss-focused route.

Rifle (Leon) Classic 70 Rifle
↑ Power Lv.2 -> Scope (required) -> Stability Lv.1

Essential for Titan Spinner Phase 1 cyst targeting. On Insanity, the Spider has more HP — Scope + Power Lv.2 makes the window longer.

Magnum (Leon) Requiem Revolver
↑ Piercing Enhancement (Exclusive — 8 Antique Coins) OR buy Infinite Ammo (12 Antique Coins)

Piercing rounds pass through the Victor Gideon Phase 2 orbital cores when aligned. Infinite Ammo (NG+ only) is the single best Insanity investment.

Primary (Grace) Freya's Needle
↑ Burst Fire Rate MAX -> Magazine Capacity MAX -> Stability Lv.2 -> Exclusive (Phantom Shot)

Phantom Shot Exclusive fires a 5-round burst instead of 3. On Insanity, Grace chapters are significantly harder due to The Girl's increased speed — more burst damage matters.

Healing (Grace) Blood Collector
↑ Tier 3 upgrade (Alloy Plate x1 + Blood x4 = full HP + regen + Elpis immunity)

Tier 3 Hemolytic Injector is a full heal + 10-second Elpis immunity. Craft one before every boss encounter as Grace.

Chapter-by-Chapter Insanity Notes

Prologue Leon

Hotel Brute hits for ~50% HP on Insanity. Stay at 8+ meters. Parry only Shoulder Charge (not Grab). Collect Mr. Raccoon #1 (parking lot) and #3 (Manager's Office shelf before safe) — same missable rules apply on Insanity.

Chapter 1 — Grace Grace

The Girl's patrol speed is ~30% faster. Her Alert Mode triggers at closer range. Activate all ground floor lights immediately. Craft 2 Flash Grenades (Hand Grenade + Flash Powder) before leaving the Director's Office. The Director's Office drawer code is 8463.

Chapter 1 — Leon Leon

Standard zombies require 3 headshots to kill. Conserve W870 — use Hatchet parry-counter finishers on low HP zombies. Every parry kill saves 3–4 rounds.

Chapter 2 — Grace Grace

Craft all 3 Hemolytic Injectors before Chunk fight. The Examination Room doorframe trick works identically on Insanity. Mr. Raccoon #10 on attic rafter — collect before Chunk defeat cutscene.

Chapter 2 — Leon Leon

Blister Borne appear in pairs on Insanity. Handle one at a time — Incendiary Round each (1 round per enemy, clears all cysts + deals fire). Never melee either while cysts are intact.

Chapter 3 Leon

Titan Spinner Phase 2 Rapid Charge has a shorter telegraph — dodge EARLY (at the start of the charging animation, not when the spider moves). Shoot all 4 explosive barrels before engaging the underbelly.

Chapter 4 Leon

RPD is the most dangerous chapter on Insanity — zombies nearly two-shot Leon. Never be surrounded. Pull enemies through doorways (1v1 in door frames). CRITICAL: collect all RPD Mr. Raccoon (#14–#20) and all 5 RPD Plant 43 seedlings before triggering the Super Tyrant fight.

Chapter 5 Leon

The Girl returns in Chapter 5 hallways on Insanity (not present on lower difficulties). Treat exactly as Care Center encounters — walk, no running, Flash Grenade ready. Plant 43 with all seedlings destroyed opens at ~40% HP — manageable even on Insanity with 3 Molotovs.

Chapter 6 Leon

The Commander Phase 2 smoke is denser on Insanity — you have approximately 2 meters of visibility instead of 4. Throw Flash Grenade the moment you hear footsteps (earlier than on Standard). Save ALL Requiem Revolver ammo (20+ rounds recommended) for Victor Gideon Phase 2.

Chapter 7 Both

Victor Phase 2: each orbital core regenerates once. NW pillar RPG trick still destroys all 4 on first wave — but you need Requiem Revolver + Piercing Enhancement for the second wave (RPG does not reload). Have 20+ Magnum Ammo. Central core: same 3-cycle strategy, dodge roll laterally on every charge.

🏅 S+ Rank Requirements

Time limit: Complete the game in under 3 hours 30 minutes total (cumulative active play time, not real time).
Death limit: Fewer than 3 total deaths across the entire playthrough.
Bonus Content: Cannot use Infinite Ammo from the Bonus Content shop (standard Exclusive upgrades are allowed).
Difficulty: Must be on Insanity difficulty.
Saves: Saving counts against time — each save takes approximately 15 seconds. Limit saves to once per chapter at most (7 saves total).

Key Time Skips for S+ Rank

SKIP
All Plant 43 seedlings: Saves 8–12 minutes of backtracking in RPD and Orphanage. Plant 43 at full HP — bring extra Molotovs.
SKIP
Blue Requests #1–#8: Skip all non-critical Blue Requests (rewards not needed at max-upgrade pace). Only do #12 Core Breach (gives RPG Round — critical for Victor Phase 2).
SKIP
Most files: Files have no gameplay impact. Reading time is wasted on S+ runs. Only collect files that are on the direct path.
SKIP
RPD Armory secondary weapons: The Matilda IMP and secondary weapons in the RPD Armory require puzzle solving time — skip on S+ routes.
SKIP
Mr. Raccoon statues (all 25): S+ Rank does not require Mr. Raccoon collection. Save 15–20 minutes across the run.
