# The Evil Within: Complete Survival Guide

Everything you need to survive Sebastian Castellanos' nightmare: resource rules, green gel upgrade priorities, the Agony Crossbow, chapter-by-chapter pointers from the 15-chapter campaign, missable achievements, difficulty modes, the Kidman and Keeper DLC, and PC settings.

*Researched September 2026 — current as of PC update 1.03 (December 2014), the last listed patch. Live games change; check the linked sources if something differs.*

## Quick Start

1. **Burn, don't shoot.** Knocked-down Haunted can get back up. A **match** on a downed enemy kills it for good, and it kills anything else in the fire too. Matches are your most efficient "weapon."
2. **Sneak kill everything you can.** Crouch, approach from behind, and hit the prompt. Sneak kills are instant and ammo-free.
3. **Spend green gel on stamina and health early.** Running away is a core skill, and the default sprint is short.
4. **Disarm traps for crossbow parts.** Bear traps, proximity bombs, and tripwire bombs can be disarmed (with a quick timing minigame) for **Parts**, which craft Agony Crossbow bolts.
5. **Smash every Madonna statue.** Each hides a **key** that opens a locker in the safe haven hospital.
6. **Look for glowing mirrors.** Stepping into a cracked mirror takes you back to the safe haven hospital to save, upgrade, and open lockers.
7. **Aim for heads, then stomp or burn.** Headshots are much more efficient; kicking or matching a downed enemy prevents it from getting back up.
8. **Hide when overwhelmed.** Lockers, beds, and closets work. Break line of sight first.
9. **Casual is fine for a first run.** Survival is the "intended" difficulty; Nightmare and AKUMU are for repeat runs.

## Core Mechanics

### Resources

| Resource | Where it comes from | What it is for |
|---|---|---|
| Green Gel | Jars, defeated enemies, containers | Permanent upgrades at the upgrade chair |
| Parts | Disarmed traps, drops | Crafting Agony Crossbow bolts |
| Matches | Scattered pickups | Burning downed enemies (and groups) |
| Syringes / Med kits | Pickups | Healing |
| Keys | Madonna statues | Safe-room lockers with ammo, gel, and more |
| Ammo | Pickups, lockers | Handgun, Shotgun, Sniper Rifle, Magnum |

Capacity for ammo is limited, which is why the "Stock" upgrade branch (extra carry capacity) is valuable.

### The safe haven

The hospital hub gives you:

- A **save** point (in-chapter save rooms are marked by the record player playing "Clair de Lune").
- The **upgrade chair**, where you spend green gel.
- **Lockers** opened by Madonna keys ("Master of Unlocking" wants all of them).
- Occasional unsettling story moments.

### Upgrades (green gel)

Upgrades are split into branches. Priorities differ by playstyle, but this order works for most runs:

| Priority | Upgrade | Why |
|---|---|---|
| 1 | Sprint duration (Physical) | Escaping is the best defense |
| 2 | Max health (Physical) | Survive mistakes and grabs |
| 3 | Match capacity / Stock | More matches means more safe kills |
| 4 | Agony Crossbow bolt damage/effects | Crossbow is your "problem solver" |
| 5 | Handgun and Shotgun (damage, capacity) | Your everyday weapons |
| 6 | Syringes / healing effectiveness | Late-game consistency |
| 7 | Sniper Rifle and Magnum | Strong but ammo-starved |

Tip: fully upgrade something rather than spreading gel thin. "My Best Friend" (one weapon fully upgraded) and "Hardbody" (all attributes) are both upgrade achievements, and the full-weapon ones stack toward "Unstoppable Arsenal."

### Weapons

| Weapon | Role |
|---|---|
| Handgun | Headshots on regular Haunted; most common ammo |
| Shotgun | Crowd control, knockdowns up close |
| Sniper Rifle | Long-range threats and weak points |
| Magnum | Emergency damage on big threats |
| Agony Crossbow | Special bolts: Harpoon, Explosive, Shock, Flash, and Freeze are the core types |
| Melee / thrown bottles | Stagger, distract, set up sneak kills ("Bloody Bar Brawl") |
| Grenades, torches, axes | Situational pickups |

Crossbow bolt tips:

- **Flash** bolts blind groups and set up sneak kills on everything nearby.
- **Freeze** bolts freeze enemies solid; follow with a shot or kick to shatter.
- **Shock** bolts are great on groups standing in water.
- **Explosive** bolts are your emergency answer to bosses and clusters.

### Stealth and combat rules

- Crouch to lower noise and enable **sneak kills**.
- Enemies have an alert indicator; if you are spotted, break line of sight and hide.
- Bottles can be thrown to distract.
- Doors and windows can funnel enemies into chokepoints for Shotgun blasts or a single match.
- Environmental hazards (traps, fire, water plus electricity) can be used against enemies.

## Chapter Pointers

The campaign has 15 chapters. These are short pointers, not full walkthroughs, focused on the moments with achievements or common deaths. Several Steam achievements are tagged with a chapter number in their description; the low-numbered ones (Ch. 1-4) are often from the Kidman DLC, so read the full description before chasing one.

| Chapter | Key moment | Tip |
|---|---|---|
| Ch. 1 | The opening escape from the Sadist through Beacon Mental Hospital | Learn hiding and sneaking here; nothing is worth fighting yet |
| Ch. 2-4 | The village and early outdoor areas; the Sadist returns | Use matches on groups at doorways and learn trap disarming |
| Ch. 5 | Rising water section ("Not Part of the Job Description": get out without a scratch) | Move fast and plan the route |
| Ch. 6 | Rescuing someone hanging on ("Everybody Gets One") | Explore fully; gel and keys are plentiful |
| Ch. 7 | A threat that "won't stay dead" ("I Don't Have Time for This!") | Avoid fighting when you do not have to |
| Ch. 8 | A quiet cave section ("Item Management": put the gun away and keep quiet) | Holster weapons to avoid noise |
| Ch. 10 | Burning a pursuer ("Bathed in Flames") | Use the environment rather than ammo |
| Ch. 12 | Protecting a bus ("Not a Scratch on Her!") | Prioritize threats that reach the vehicle |
| Ch. 14 | Getting a generator panel running ("Entry Level Electrician") | Explore before you commit |
| Ch. 15 | The finale | Stock up; bring explosives and Magnum ammo |

Notable bosses and threats include **Ruvik** (the main antagonist), **the Keeper** (the box-headed executioner), **the Sadist** (chainsaw), and the multi-limbed **Laura**. General rules: fire works on Laura, the Keeper respawns from its safe-boxes in its chapter, and running is always an option.

## Difficulty Modes

| Difficulty | Available | Notes |
|---|---|---|
| Casual | From start | Forgiving; "First Step into Darkness" |
| Survival | From start | Intended balance; "Another Day on the Job" |
| Nightmare | After finishing the game | Much harder; "Master of Horror" |
| AKUMU | After finishing the game | Almost anything kills you in one hit; "You Asked For It." |

New Game+ carries your upgrades, which makes Nightmare and AKUMU far more manageable.

## Achievements Worth Planning

| Achievement | Requirement | How to handle |
|---|---|---|
| It Is What It Is | Finish without upgrading any skills with green gel | Dedicated run; Casual recommended |
| The Quick and the Dead | Clear under 5 hours | New Game+ with upgrades; skip optional exploration |
| There Will Not Be Blood | Get through the hotel without being spotted or killing enemies (Ch. 4) | Kidman DLC hotel section; patience and stealth |
| Every Nook and Cranny | Collect every collectable | Use chapter select after finishing |
| Master of Unlocking | Open all lockers in the save room | Smash every Madonna statue |
| Unstoppable Arsenal | Fully upgrade all weapons | Late or NG+ |
| Full House | 5 kills with each type of Agony Bolt | Mix bolts throughout |
| Drop It Like It's Hot | Kill 3 living enemies with one match | Wait for a group at a trap or doorway |
| Blow Up the Playing Field | 10 kills with a secret explosive weapon | Available after finishing the game |
| Kurayami achievements | Clear the DLC on KURAYAMI Mode | Kidman DLC post-game |

Chapter select exists after completion, so missables are really "missed for this run" rather than permanent.

## DLC

| DLC | You play as | Focus |
|---|---|---|
| The Assignment | Juli Kidman | Stealth-only survival, no guns for most of it |
| The Consequence | Juli Kidman | Continuation; more tools, bigger reveals |
| The Executioner | The Keeper | First-person brawler/beat-'em-up |

Both Kidman DLCs have collectibles ("Personnel Files," "Research Documents") and hidden letters. The DLC is worth it if you liked the main story's mystery; Kidman's side explains much of what Sebastian does not see.

## PC Settings and Fixes

- A post-launch update added a **30/60 FPS cap** toggle and a **letterbox** (black bars) toggle in settings. Use both if your PC can handle 60.
- Higher-framerate gameplay issues were addressed in that update; stick to the official 30 or 60 caps rather than forcing unlimited framerates through drivers.
- Update 1.03 fixed a "Power of Three" achievement issue and made count-based achievement progress persist when loading older saves.

## Common Mistakes to Avoid

- **Leaving downed enemies unburned.** They can get back up. Kick, stomp, or burn.
- **Unloading into bodies.** Headshots or knockdowns followed by matches are far more ammo-efficient.
- **Spreading green gel across everything.** Commit to sprint, health, and one or two weapons first.
- **Walking into traps.** Watch for tripwires and floor plates, and disarm them for Parts instead.
- **Ignoring Madonna statues.** The locker rewards add up to a lot of ammo and gel.
- **Fighting the chapter "unkillables."** Some pursuers are meant to be run from.

## Advanced Tips

- **Door funnel plus match:** lure a pack to a doorway, knock one down, drop a match. The flames spread to the others.
- **Flash bolt plus sneak kill chain:** one Flash bolt blinds a group; walk in and sneak kill several.
- **Save gel for NG+ speedruns.** On repeat runs, upgrade sprint and damage early to skip fights.
- **Use bottles.** A thrown bottle distracts an enemy and sets up a sneak kill.
- **Crossbow crafting discipline:** keep Parts for Explosive and Freeze bolts before bosses.

## FAQ

**How long is The Evil Within?**
15 chapters; a first careful run is typically in the 15-20 hour range. "The Quick and the Dead" asks for under 5 hours on a practiced run.

**Is The Evil Within scarier than the sequel?**
It is more linear and more resource-starved; The Evil Within 2 (October 2017) is more open.

**What do the keys do?**
They open lockers in the safe haven hospital, which contain ammo, supplies, and green gel.

**How do I get back to the safe haven?**
Walk into a cracked mirror.

**What is AKUMU mode?**
The hardest difficulty, where almost everything kills you in one hit. It unlocks after finishing the game.

**Is it worth getting the DLC?**
Yes if you enjoyed the story. The Assignment and The Consequence answer many of the base game's questions through Kidman.

**Can I remove the black bars?**
Yes. A patch added a letterbox toggle to settings.
