How to Host a Jurassic Terror Server

Start with at least 6 GB of RAM. Jurassic Terror runs on Forge 1.20.1 with custom dinosaur AI and spawn logic layered on top of standard world generation, and that AI load is what pushes the floor up from a vanilla-ish pack — 6 GB is where the pack itself sets the bar, not a generic modpack guess.

Import the modpack directly instead of guessing from a client export. CoalHost's installer pulls the exact Jurassic Terror server pack, so you avoid missing server-side configs or mismatched mod jars that a hand-copied client folder tends to drop.

Watch the console through the first full boot. Because this pack leans into horror pacing with aggressive dinosaur AI and tense nighttime encounters, you want to confirm the mob spawn tables and AI behavior packs load without errors before anyone sets foot in the world — a silent AI load failure here just means dinosaurs that don't behave as intended, not a crash you'd notice right away.

Only invite players once that first boot finishes clean and the server is sitting idle without errors. Jurassic Terror's survival-horror design means a shaky first session (lag during a night encounter, a half-loaded AI mod) undercuts the exact tension the pack is built around.

Take a backup before importing an existing world, updating Forge or any dinosaur-AI mod, or touching configs. In a horror-survival pack like this, players' progress is tied to scarce resources and fragile base defenses built up over tense nights — losing that to an avoidable mistake is a bigger deal than it would be in a casual pack.
