Abyssal Station

Endless tower defense

Abyssal Station is a PC endless tower defense game set in 2187. Kerr Industries built a station above a rift at the bottom of sector 7, hoping to harvest its biomass. The rift is an eyelid, and something beyond it is attacking. You build defenses around the station’s core and try to hold off successive waves; a run ends when the core falls.

Each run generates a new symmetrical station, sky and set of rolls. Enemies include swarms, ironclads, burrowers and parasites that attack your guns from inside. The game has no final wave: your progress is measured by how deep you get.
