Alternate Realities: Archangel’s Plague Virus

The mod follows an infection that began when the code of the Minecraft world was twisted. Shapeshifting entities called Alternates distort the world and create chaos as the plague spreads. Players uncover the secrets of these beings while the story unfolds through sound, shadow and strange structures that hide clues. The themes include horror, supernatural elements, eerie sounds and references to fictional mythology, drawing on real religions, historical figures and analog horror.

Alternates come in several kinds. Standard Alternates have human-like forms and eerie shifting faces, and some can mimic players and villagers. N-Type Alternates are faster and less stable, able to vanish in light. Controllable Alternate Commanders lead other entities, and Spectral Alternates are energy-based and phase through blocks. Several governments and factions form across the world, including authoritarian regimes that seek to weaponize Alternate energy and an independent alliance of settlers and scientists.
