Humanities Last War: Alien Invasion RPG

Earth has been overrun by the Xy’Thal, an enigmatic alien race wielding gravity-defying technology and biomechanical weaponry. The remnants of humanity survive in hidden enclaves, scavenging alien tech while planning a desperate resistance.

A mix of sci-fi horror and dystopian survival, where every day is a fight against superior alien oppressors. The tone is grim and suspenseful, but there is a sliver of hope as humanity discovers the aliens have weaknesses.

The year is 2147, three decades after the initial invasion that saw Earth's major cities fall within weeks. Human civilization is fragmented, with underground bunkers and mobile outposts replacing once-thriving metropolises.

• The Xy’Thal Overlords – The alien rulers of Earth, emotionless but highly strategic, enforcing their rule with biomechanical sentinels.
• The Revenant Coalition – A loosely connected network of human resistance fighters, scientists, and ex-military strategists.
• The Scavenger Guilds – Nomadic survivors who trade in alien technology and black-market supplies, often working for the highest bidder.
• The Apostles of Ascension – A human cult that worships the Xy’Thal, believing surrender will lead to enlightenment.

• Humanity struggles to uncover the Xy’Thal’s true weaknesses before total extermination.
• The Revenant Coalition and Scavenger Guilds clash over stolen alien tech.
• The Apostles of Ascension sabotage resistance efforts, hoping to prove their loyalty to the invaders.
• Internal alien power struggles hint at a possible civil war among the Xy’Thal.

• The Black Vault – A secret underground human research facility attempting to reverse-engineer alien technology.
• Neo-Ruins of New York – A shattered metropolis where scavengers hunt for supplies while avoiding alien patrols.
• The Sky Bastion – A massive floating Xy’Thal fortress, home to their ruling council.
• The Wastelands – Once-thriving regions now irradiated and crawling with alien mutations.

• Humanity has abandoned traditional nation-states, operating in scattered city-states and guerrilla cells.
• Alien technology has begun merging with human biology, leading to cybernetic warriors and experimental hybrids.
• Stories and myths about the Xy’Thal’s origins are spreading, with some believing they fled their own dying world.
• Music and art have become underground resistance tools, used to spread hope and encrypted messages.

Trust is fragile, as betrayal and desperation run rampant in the remnants of human society. While survival is paramount, small acts of defiance—graffiti, encrypted radio broadcasts, and daring raids—keep the flame of rebellion alive.

The Xy’Thal are a highly advanced, biomechanical alien species with sleek, chitinous exoskeletons and glowing, lattice-like neural structures, allowing them to communicate telepathically. Lacking individual emotions but possessing a hive-mind intelligence, they see humanity as a resource to be assimilated or eradicated, with little regard for Earth’s former inhabitants.
