"Abyssal Swarm" is a military science fiction survivor game with different guns, drones, turrets, vehicles, and mechas. You are a member of the space special forces, fighting in the abyss against endless swarms of insects.
Abyssal Swarm
SteamWhen the mushroom clouds of nuclear explosions bloomed on the horizon for the last time, human civilization entered its darkest chapter. Radiation clouds shrouded the sky, and arthropods lurking deep within the earth underwent frenzied evolution under gamma radiation, swarming across continents with their steel-blue fluorescent exoskeletons. In just seven years, these abyssal predators devoured 96% of habitable zones. Surviving world leaders signed the Ark Protocol aboard orbital stations, retreating humanity's final military forces to low-Earth orbit.
Yet hope emerged fifteen years after the exodus—deep-space probes detected signs of Earth's ecological self-recovery. As an elite "Scavenger" soldier, you descend to the ravaged surface armed with a quantum communication array, establishing forward bases amidst sky-darkening insect tides. Deploy eight tactical support systems: from portable combat drones and all-terrain armored vehicles to deployable smart turrets and plasma-cutter-equipped battle mechs. Earn new airdrop supplies every three minutes of survival, but beware—the swarm evolves faster than you can adapt.
This is no mere survival game—it's humanity's counterattack against Earth's mutated ecosystem. Amid radiation-scorched ruins and tremors from tunneling worker ants, every tactical decision accelerates humanity's return timeline. Every trigger pull is an oath to reclaim existence.
