Crude Oil Endings Guide: All Endings & How to Unlock

Introduction to Crude Oil Endings

Crude Oil offers multiple endings based on your choices and actions throughout the story. As a sentient oil blob fleeing from a ruthless oil corporation, your journey can conclude in several dramatically different ways. This guide covers all known endings, the requirements to unlock each one, and tips to achieve your desired conclusion. Whether you aim to escape, retaliate, or merge with the machine, your path will depend on key decisions in the campaign.

For an overview of the main story, check out the Story Campaign Guide.

Ending 1: The Escape Ending

The most straightforward ending is the Escape Ending. To unlock it, you must avoid heavy confrontation with the corporation and focus solely on reaching the designated extraction point.

Requirements:

• Complete all main story missions without destroying more than three corporate oil rigs.
• Never upgrade the "Aggression" skill tree.
• Choose dialogue options that prioritize fleeing over fighting.

This ending sees your oil blob successfully reaching a hidden pipeline that leads to a remote, unpolluted ocean. While you survive, the corporation continues its destructive operations elsewhere. It is considered the "neutral" conclusion.

Ending 2: The Revenge Ending

The Revenge Ending is for players who want to fight back. This path requires you to embrace your destructive potential and systematically dismantle the corporation's infrastructure.

Requirements:

• Destroy at least ten corporate oil rigs during the campaign.
• Fully upgrade the "Aggression" and "Mass" skill trees.
• Choose the "Fight" option in every critical encounter.

In this ending, you grow to an enormous size, flood the corporation’s headquarters, and wash their executives into the sewers. The world is freed from their pollution, but your oil form becomes too unstable to survive. You dissolve into the earth, leaving a legacy of liberation. For help with upgrades, see the Upgrades Guide.

Ending 3: The Symbiosis Ending

The Symbiosis Ending is the most complex and requires careful balancing. You must cooperate with a rogue AI inside the corporation's main refinery.

Requirements:

• Complete the "AI Core" side quest (found in the Refinery level).
• Collect all 12 data fragments scattered across the game.
• Upgrade the "Control" skill tree to at least level 5.
• Do not destroy the AI's core during the final mission.

If successful, your oil consciousness merges with the AI, creating a new hybrid entity that can control both organic and mechanical systems. The corporation is converted into a clean energy provider. This ending is often considered the "best" outcome. For more on game mechanics, refer to the Mechanics Guide.

Ending 4: The Sacrifice Ending

The Sacrifice Ending is a hidden ending that requires specific actions in the final level.

Requirements:

• Have less than 30% health when entering the final boss arena.
• Use the "Containment Protocol" item (found in the Laboratory level).
• Refuse to absorb the final boss's oil.

Your character chooses to contain the corporation's toxic waste within itself, then detonates a purification bomb. Your oil body is destroyed, but the land is cleansed. This ending unlocks a special achievement and a post-credits scene showing new life sprouting from the soil. For a full list of achievements, see the Achievements Guide.

Tips for Unlocking All Endings

To see all endings in a single playthrough, you'll need to save your game at key decision points. Here are some tips:

Key decision points to save at:

• After completing the "Refinery Infiltration" mission.
• Before entering the final area (the "Core Chamber").
• When the rogue AI first contacts you.

Recommended order for endings:

1. Escape (easiest, good for first playthrough).
2. Revenge (requires aggressive playstyle).
3. Symbiosis (needs exploration and side quests).
4. Sacrifice (requires specific item and low health).
