Halcyon

The year is 2506. A vestige of humankind, you’ve been sent to Earth on the faint hopes that you will find more than the corpse of a once hospitable planet. Instead, you find a landscape blooming with lush, mutated new life.

About the Game



Rediscover Earth


An era of birth and regrowth breathes new life into the world…but not for humanity. Fight your way through giant insects, mutated birds, and much, much worse. All against the backdrop of stunning parallax environments, colorful backdrops, and the hauntingly beautiful remnants of a long departed Anthropocene.

Fight, Fly, Survive


Shoot your way through ground and aerial combat encounters, armed only with your plasma rifle and flight bot. Respite is scarce. Supplies are scarcer. Your journey will be marked by the corpses of those who came before you.

Fulfill Humanity’s Last Hope


Sent by Mothership Terra, you will be pushed to your limits as you battle through unique biomes and hazardous hellscapes. You will face a myriad of malformed creatures thriving in the now fertile wasteland your people left behind. Can you survive this inhuman halcyon?

A Nostalgic Indie Debut


A game by Raleigh and Keirdan. A triumphant debut title from Real Action Labs, this 2D pixel art side-scrolling shooter is made possible by the hard work and passion of two independent developers.
