Beyond Containment - IGS

Containment failed.
The Eclipse changed them. Now they are loose.

Beyond Containment – IGS is the official creature and hostile-entity expansion for the Eclipse Protocol universe, developed by Immortal Game Studios.

The mod adds corrupted lifeforms, unstable anomalies, escaped experiments, biological distortions, and Eclipse-born entities to Minecraft.

The world of Eclipse Protocol is already broken.

Beyond Containment makes it worse.

---

Overview

Restricted facilities studied organisms, experimental treatments, anomalies, and forces that were not fully understood.

When the Eclipse disrupted power, communication, security systems, and military control, containment failed.

Research sites went silent.

Blacksite systems collapsed.

The entities inside those locations escaped into the world.

Beyond Containment represents the biological and anomalous side of Eclipse Protocol.

Hostile Entity Design

The creatures in Beyond Containment are connected to the setting and lore of Eclipse Protocol.

Their origins include:

• Failed containment procedures
• Corrupted experiments
• Eclipse energy
• Biological mutation
• Abandoned research programs
• Infected humans or animals
• Unstable anomalies
• Classified military projects
• Unknown organisms

The mod focuses on hostile encounters that create fear, pressure, uncertainty, and survival risk.

Gameplay Focus

Beyond Containment adds threats designed for:

• Direct combat
• Ambush encounters
• Dark environments
• Restricted facilities
• Corrupted areas
• Underground exploration
• High-risk survival zones
• Lore-connected encounters

The entities make exploration more dangerous and give abandoned locations a stronger connection to the collapse.

• Abandoned cities
• Red zones
• Forests
• Underground facilities
• Research laboratories
• Military bunkers
• Blacksite complexes
• Ruined settlements
• Industrial areas
• Corrupted regions

The entities support the identity of these environments and reinforce the feeling that something escaped before the player arrived.

Visual and Design Direction

Beyond Containment uses a dark biological-horror style.

Creature designs include elements such as:

• Blackened or damaged bodies
• Mutated silhouettes
• Purple glowing eyes
• Unstable Eclipse energy
• Exposed biological structures
• Experimental implants
• Asymmetrical mutations
• Containment markings
• Worn restraints
• Signs of corruption

The mod does not use unrelated fantasy-monster design. Every entity belongs to the broken scientific, military, and anomalous world of Eclipse Protocol.

Lore Direction

Containment failed.

Blacksite systems collapsed, research teams disappeared, and restricted facilities continued operating without reliable human control.

Some entities were once human.

Some were altered animals or organisms.

Some were created through experiments.

Others are connected directly to the Eclipse.

Beyond Containment shows the consequences of the unknown escaping into the world.
