Lead a team of scientists conducting genetic experiments on local wildlife on the ocean floor. Keep your population sane, obedient and alive as you expand your base and discover the secrets of cloning and genetic research. Improve life and progress in your facility by researching advanced technologies. The fate of your crew is in your hands! Make crucial decisions through the event system.
Ensure the survival of your crew by planning, placing and building essential infrastructure for manufacturing, research and life support. Expand and optimize your base and its available resources. Connect your buildings and mining facilities efficiently with tunnels and powerlines. Conquer the uneven terrain of the ocean floor with clever planning and vertical construction.

Your crew senses it, and so do you. Something is lurking at the edge of darkness, slithering and seething. Darkness is danger, light is safety. Do not turn off the light.
Surviving the Abyss for PC starts at €19.18 at G2A, a Steam gift, which is 4% under the €19.99 it costs on the official store.
Supply is thin — 7 offers from 4 stores — and thin supply keeps prices steady rather than falling.
That puts it 4% under its average of €19.99 since 2024, so today is a better entry point than most days of its life.
That €19.99 key is expensive for what it usually costs.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
By format: Steam Gift from €19.18 and Steam Key from €19.99.
