Beyond Containment – IGS

Beyond Containment – IGS is an official Immortal Game Studios creature and entity expansion for Minecraft, built for the Eclipse Protocol universe.

This mod brings the hostile results of the Eclipse into the game: corrupted lifeforms, unstable anomalies, containment breaches, and dangerous Eclipse-born entities that were never meant to exist outside controlled environments.

The world of Eclipse Protocol is already broken. Beyond Containment makes it worse.

Overview

Beyond Containment adds custom Eclipse mobs designed around fear, pressure, atmosphere, and survival gameplay.

These entities are not normal monsters. They are the result of failed containment, corrupted experiments, unknown Eclipse energy, and biological distortion caused by forces no one fully understands.

Some creatures hunt directly.
Some stalk from the darkness.
Some feel more like anomalies than living beings.

Every encounter is designed to make the world feel more dangerous, unpredictable, and connected to the deeper lore of Eclipse Protocol.

Gameplay Focus

Beyond Containment focuses on hostile entity encounters, atmospheric horror, and survival pressure.

The mod is designed to make exploration more dangerous by adding threats that fit abandoned cities, ruined facilities, red zones, forests, bunkers, underground structures, and corrupted areas.

Players are meant to feel that something escaped before they arrived.

Visual & Design Direction

Beyond Containment uses a dark Eclipse-based creature style.

Mobs are designed with blackened bodies, corrupted textures, purple glowing eyes, unstable Eclipse energy, mutated silhouettes, and a threatening post-apocalyptic presence.

The goal is not to add random fantasy monsters, but to create creatures that feel like they belong to a broken world shaped by the Eclipse.

Lore Direction

Containment failed.

Whatever was studied, created, or discovered inside restricted zones is no longer locked away. Blacksite systems collapsed, research sites went silent, and the things left behind now move through the ruins.

Some were infected.
Some were changed.
Some may never have been human or natural at all.

Beyond Containment expands the darker side of Eclipse Protocol by showing what happens when the unknown is no longer contained.

Notes

Beyond Containment – IGS is intended to be used together with Eclipse Protocol – IGS and Project Dawn - IGS.

It serves as the main entity and hostile creature expansion for the Eclipse Protocol universe and will continue to expand with new mobs, variants, behaviors, animations, drops, and lore-connected threats.
