Setting Up Offline Raid Protection (ORP) in Ark

Ark Guide • Updated Feb 21, 2026

Setting Up Offline Raid Protection (ORP) in Ark

One of the quickest ways to lose a player base on an unofficial PvP server is offline raiding. Ark features built-in Offline Raid Protection (ORP) that makes bases invulnerable when tribes log off, ensuring combat only happens when both sides can fight back.

Activating Default ORP

Ark’s native ORP system is enabled entirely via the server configuration files. Navigate to your GameUserSettings.ini and locate the [ServerSettings] header.

PreventOfflinePvP=True
PreventOfflinePvPInterval=900
ShowFloatingDamageText=True
AutoDestroyDecayedDinos=True

Crucial Settings Breakdown

  • PreventOfflinePvP=True: Turns on the global feature.
  • PreventOfflinePvPInterval=900: Highly crucial. This is the delay in seconds AFTER the final tribe member logs off before invulnerability initiates. 900 seconds (15 minutes) prevents "combat logging"—where a tribe under heavy siege abruptly pulls the plug on the internet to artificially shield their base mid-fight.

Handling Cave building and ORP Abuse

A major flaw with ORP is "pin-coding." A player builds an invincible box on an alternate account (which stays offline permanently), puts a pin code on the door, and uses it to safely store loot on the main account. To combat this abuse on dedicated servers, admins frequently use ORP Mods from the Steam Workshop instead of the native setting.

Mod Recommendation: If you are running heavily modded PvP, utilizing specific mods like Lethal's ORP provides magnitudes more control—allowing turrets to deal 3x damage while offline rather than giving literal invulnerability, creating a much more balanced meta.
