Abusing Valheim's Physics Engine to Land a Market Garden

Storyline (context)

• The video doesn’t follow a traditional “quest storyline.” Instead, it spotlights a Valheim physics exploit centered around an abyssal harpoon (and related movement/physics bugs).
• The goal is to attempt something “historically” new in the community: the first recorded “market garden” in Valheim—landing and harvesting/killing mobs by manipulating their placement with physics.

Gameplay / experiment overview

Key mechanic exploited: Abyssal Harpoon

• The harpoon is used to pull mobs toward the player.
• Normally, this pulls mobs to a fairly consistent distance, making kills easier.
• The exploit emerges when:
  • The target gets stuck on terrain/objects, and you pull it farther than usual.
  • This causes stacking applied force, pulling players as well (in PvP-enabled scenarios).
  • The result can resemble catapult-like situations.

“Chair + PvP” chaos (early proof)

• The creator sets up a PvP test by:
  • Getting someone stuck in a chair (to make unintended physics easier to trigger).
  • Using the harpoon to pull them into wild positions and distances.
• The point is to demonstrate that players can be forcibly repositioned, not just mobs.

Main “Market Garden” plan (step-by-step)

1. Find the highest spot possible and build a launch pad.
2. Test the launch to determine where targets will land.
3. Dig a pit at the landing site and fill it with mobs.
4. Perform the launch to land the “first market garden in Valheim history.”

Problem #1: Mobs don’t spawn in time

• At high launch speeds, the game’s render/despawn/spawn timing can prevent mobs from appearing where needed when the player arrives.
• This initially made the whole plan seem impossible.

Adaptation / strategy upgrade: Vertical “tower” method

• Solution: Build a tower so the launch ends above the mobs, then drop/pull while avoiding horizontal render-distance issues.
• Because leaving the horizontal render area can cause despawn/desync, the team tried to keep the action within the right bounds.

Extra movement breakthrough (controls quirk)

• The creator identifies a movement quirk:
  • Pressing/holding movement while the view/camera faces backwards changes movement/propulsion behavior.
• Outcome:
  • They discover a reliable way to go straight up (a more stable vertical launch compared to earlier sideways attempts).

Outcome

• The “for real” attempt succeeds:
  • They complete what they claim is the first recorded Valheim market garden using the harpoon/physics setup.
• The creator then immediately dies during/after the success (“if that doesn’t get us into Valhalla…”).
• This emphasizes that the exploit is powerful, but also high-risk.

Key tips / takeaways

• The harpoon works best when targets can get stuck on objects/terrain—force can build up unexpectedly.
• Render distance matters: at extreme speeds, mobs may not spawn where needed.
• Use a vertical tower approach to avoid horizontal render issues.
• Experiment with camera/view-relative inputs; a “backwards camera + W” quirk enables extreme vertical movement.
• Expect performance issues at extreme speeds (the game may not render everything quickly enough).
