Ultrakill: 100 Save File Best

Master the Chaos: Everything You Need to Know About the ULTRAKILL 100% Save File

If you’ve spent any time in the blood-soaked, neon-drenched layers of Hell, you know that ULTRAKILL isn't just a retro-shooter—it’s a test of mechanical perfection. Whether you are a speedrunner looking for a practice canvas or a player who simply wants to experience the absolute peak of V1’s arsenal without the 100-hour grind, an ULTRAKILL 100% save file is the ultimate shortcut.

In this guide, we’ll dive into what a complete save offers, how to install it safely, and why "completion" in ULTRAKILL is a badge of honor. What Does a 100% Save File Include?

ULTRAKILL is currently in Early Access, meaning "100%" is a moving target. However, a high-quality community save file typically provides:

All Weapons & Variants: Immediate access to the Marksman Revolver, Rocket Launcher, and the devastating Railcannon variants.

Perfect Ranks (P-Ranks): Every level in Preludes, Act I, and Act II cleared with a P-Rank (meaning you hit the requirements for kills, time, and style without dying). ultrakill 100 save file

Secret Missions Unlocked: Access to the weirder side of Hell, including the horror-themed levels and fishing minigames.

Prime Sanctums: This is the big one. A 100% save grants access to P-1 (Soul Survivor) and P-2 (Wait of the World), allowing you to fight Minos Prime and Sisyphus Prime immediately.

The Cyber Grind: High-level waves unlocked so you can test your mettle against infinite waves of enemies with all environmental modifiers available. Why Use a 100% Save File? 1. Skip the "Skill Wall" for Prime Bosses

The Prime Sanctums are arguably the hardest boss fights in modern gaming. To unlock them naturally, you must P-Rank every single level in their respective Acts. For many, the challenge of P-Ranking "P-2" is a gatekeeper. A save file lets you jump straight into the ring with Sisyphus Prime. 2. Sandbox and Testing

Want to practice your "Projectile Boosts" or "Coin Adding" techniques in the Sandbox mode with every enemy type unlocked? A complete save populates your spawn menu with every husk, machine, and demon in the game. 3. Modding and Custom Maps Master the Chaos: Everything You Need to Know

If you are moving between PCs or experimenting with the Angry Level Loader mod, having a base 100% save ensures that your character's power level is consistent across custom content. How to Install an ULTRAKILL 100% Save File

Installing a save file is straightforward, but you must be careful not to overwrite your own progress permanently. Locate Your Save Folder:

Navigate to your Steam library folder. Usually: C:\Program Files (x86)\Steam\steamapps\common\ULTRAKILL\Saves. Backup Your Current Data:

Copy your existing Slot1 or Slot2 folder to your desktop. Do not skip this step. Download the Save:

Find a reputable source (like Speedrun.com or the ULTRAKILL Discord). The file will usually be named Slot1. Replace and Launch: Legality: Sharing or using save files is generally

Drop the downloaded folder into the Saves directory. Disable Steam Cloud Sync temporarily to prevent Steam from overwriting the new file with your old cloud data. Confirm:

Launch the game and check the "Select Slot" menu. You should see a beautiful row of gold "P" icons. The Ultimate Challenge: Should You Use One?

While an ULTRAKILL 100% save file is a great tool, remember that the game’s core philosophy is Mastery. There is an incomparable rush to finally seeing that "P" rank appear after thirty failed attempts at a level like A Shot in the Dark.

If you use a save file to skip the grind, we recommend still going back and trying to earn those ranks yourself. The weapons are just tools; the real "100%" is the skill you develop along the way. MANKIND IS DEAD. BLOOD IS FUEL. HELL IS FULL.

Legality, safety, and ethical considerations

Legality: Sharing or using save files is generally legal for personal use. However, distributing copyrighted in-game assets or bypassing DRM could raise terms-of-service or platform-policy issues. Always respect the developer’s terms and platform rules.
Safety: Downloading save files from unknown sources risks malware. Only download from trusted community sites or inspect the file before use.
Fair-play: Using edited saves in multiplayer or leaderboards is unethical and may violate rules; restrict edited saves to single-player, offline, or testing contexts.
Corruption risk: Manual editing can corrupt files; back up originals before modifying.

What a 100% Save File Gives You

Full Arsenal – Every gun, variant, alt fire, and upgrade.
All Levels + Secrets Unlocked – Jump to any level, including P-1 (Cerberus fight), P-2 (Sisyphus Prime), and future P-3.
Developer Museum Access – Hidden room with lore, test enemies, and nods to Hakita (dev).
Max Style Capabilities – Allows theorycrafting and speedrun practice from a complete state.

4. How to Install a 100% Save File (Step-by-Step)

Locate your Ultrakill save folder:
C:\Users\[YourName]\AppData\Local\ULTRAKILL\
Backup the existing SaveFile.sav (rename to SaveFile_backup.sav).
Download the 100% .sav file and place it in the folder.
Launch the game – all levels, weapons, and ranks should be unlocked.

2. Secret Discovery

ULTRAKILL is notorious for its secret encounters. These include:

Secret Levels: Such as "0-S: Something Wicked" or the chaotic "5-S: The Sewers."
Soul Orbs: Hidden collectibles that unlock the game's lore terminals.
Challenge Nooks: Hidden areas containing the Slab Revolver variants.

3. You are a modder/tester.

The Ultrakill modding scene is vibrant. If you want to test a custom level or a gameplay tweak, you need all weapons and abilities unlocked. A 100% save file is the "debug mode" for creators.

Manual Edit Alternative

If you only want to unlock specific levels or weapons without full 100%:

Open SaveFile0.sav with Notepad++ or VS Code.
Look for "levelProgress" and "weaponUnlocks" – edit booleans/ranks carefully.
Back up first – corruption is easy.
