About Halcyon
Halcyon is a 2D pixel-art side-scrolling shooter set on an Earth where nature has regrown, but humanity is gone. Sent by Mothership Terra, you fight through the fertile wasteland and its hazardous biomes, facing giant insects, mutated birds and other malformed creatures.
Ground and aerial combat
You shoot your way through ground and aerial encounters with a plasma rifle and a flight bot. Supplies are scarce and respite is limited; the journey is marked by the corpses of those who came before you.
A regrown Earth
The world features parallax environments, colorful backdrops and remnants of the Anthropocene. You battle through distinct biomes and hazardous hellscapes as you try to survive the world humanity left behind.
