About
In the 22nd century, a meteor strike reshaped the face of Earth.
Ancient algae dormant for hundreds of millions of years awakened and released massive volumes of oxygen, pushing the global oxygen concentration up to 35%. Unable to adapt to this hyperoxic world, humanity can only venture out of shelters relying on time-limited oxygen suppressants, exploring and struggling to survive across perilous wastelands.
The surface now belongs entirely to mutated lifeforms. Giant insects roam the wilderness, and dinosaurs have reclaimed their place in the food chain. Every deep expedition into restricted zones is a gamble between valuable loot and certain death.
Venturing deep into restricted zones grants access to greater loot, yet it also brings grave dangers: expiring suppressants, encounters with mutated creatures, and the risk of being trapped with no way to extract.
Push deeper, or extract immediately?
Use cover, terrain, elevation differences, combined abilities and your creatures’ unique traits to defeat foes far stronger than your squad.
Stats do not win battles — your choices do.
Capture dinosaurs and mutated insects native to this hyperoxic world.
Every species comes with distinct traits, abilities and growth paths.
The greatest threat in this land is not the monsters.
It is the air itself.
Your window to act is limited by the lifespan of your oxygen suppressants. Every expedition demands you complete your objectives and extract safely before time runs out.
