BioCraft: Alien

Formerly known during early development as Weyland-Yutani Core (AlienCraft).

BioCraft: Alien brings the terrifying lifecycle of the Alien universe into Minecraft through data-driven gameplay, modular systems, and a growing laboratory experience.

Discover mysterious Ovomorphs, evade relentless Facehuggers, survive implantation, and watch a Xenomorph colony grow from a single egg into a living hive. Capture specimens, contain dangerous organisms, observe their behavior, and build research facilities around them.

Features

Complete Xenomorph Lifecycle

Experience the full lifecycle from beginning to end.

• Ovomorph (Egg)
• Facehugger
• Gestating Host
• Chestburster
• Xenomorph Drone
• Xenomorph Queen

Every stage progresses naturally with AI-driven behavior, maturation, and persistence across saves.

Laboratory Systems

Version 1.2 adds the Lab Manual and Biological Profiles on top of the laboratory foundation from 1.1. Version 1.2.1 adds survival crafting recipes for the laboratory blocks and empty tools.

Current laboratory features include:

• Lab Manual with organism pages, stacked multiblock previews, and machine notes
• Biological Profile catalog for vanilla organisms, the human host, and the xenomorph lifecycle
• Innate characteristics, including acidic blood and lifecycle abilities
• DNA Analyzer, Containment Pen, and Specimen Pod displays of identity and contributing source
• Spider-derived climbing for a Chestburster with a spider contributing source
• Generic LivingEntity containment system
• Scalable Containment Pens
• Motion Tracker
• Specimen observation framework
• Research record infrastructure
• Capture Net for transporting specimens
• Laboratory management interface
• Lab Manual recovery recipe (book and iron) and the injection syringe recipe
• Survival crafting recipes for the laboratory blocks and empty tools, with pickaxe drops for the placeable blocks

The laboratory architecture is designed to support more research equipment, specimen analysis, and additional organisms without replacing existing gameplay.

AI & Gameplay

• Intelligent Xenomorph behaviors
• Facehugger attachment and implantation
• Chestburster emergence
• Queen egg laying
• Hive expansion
• Data-driven AI configuration
• Persistent lifecycle progression
• Save/load safe entity systems

Architecture

BioCraft: Alien is built around a modular architecture emphasizing:

• Data-driven gameplay
• Clear ownership boundaries
• Reusable gameplay systems
• Long-term maintainability
• Extensibility for future content

Most gameplay tuning is controlled through JSON resources rather than hardcoded values.

Current Status

The project now includes:

• The complete playable Xenomorph lifecycle
• A reusable laboratory framework for containment, observation, and research
• A Lab Manual for organisms, structures, and machine operation
• Biological Profiles for organism identity and innate characteristics

Natural world spawning remains disabled by design. Specimens are currently introduced through Creative Mode, commands, or laboratory workflows.

Many visual assets—including custom textures, sounds, and additional animations—remain works in progress and will continue to improve over future releases.

Future updates will expand:

• Further biological manifestations and host differentiation
• Additional host species
• New Xenomorph forms
• Research equipment
• Laboratory machinery
• Alien Earth creatures
• Progression systems
