Abyss Salvage

Abyss Salvage is a free idle game about lowering a salvage rig into the deep and letting it earn while you get on with something else. There is nothing to click for score and no reflexes involved: the drill runs on its own, online and offline, and your job is to decide what the rig should be good at.

That decision is the whole game. Your reactor hands out a small number of power pips, and four systems compete for them. The Drill Array is what actually pays. The Thrusters fight the current that tries to push you back up. Hull Plating is the only thing between the rig and the pressure. The Floodlights matter because in dark water you cannot salvage what you cannot see. There are never enough pips for all four, so every configuration is a bet.

What keeps it from turning into the usual "same thing, bigger numbers" is that each depth band leans on a different system. The kelp reef drags at you and wants thrust. The twilight zone kills the sunlight and wants lumen. The midnight zone is where pressure first becomes real and starts bleeding your hull. The trench sends currents straight up the canyon at you. Cross into a new band and the rig that was perfectly tuned a minute ago is suddenly wrong, and you go back to the Power tab and re-cut the pie.

By default the rig parks itself at the deepest point your hull can hold and mines there safely. You can also override that limiter and keep diving, which pays far better and slowly tears the hull open — a hull breach forces an emergency ascent, so pushing deep is a genuine risk you choose to take rather than a punishment the game inflicts.

When a run has given what it can, you surface and refit: the rig is scrapped and traded for Pearls, which permanently raise both your income and every module rating, so the next rig starts stronger and reaches deeper than the last. Pearls are paid for how deep you got and for how much you hauled, which means that once you have conquered the depth chart there is still a reason to run — the question becomes how much a single rig can pull out.

The water changes as you sink, across four worlds. Sunlit Shallows has light shafts and kelp; Twilight Depths loses the sun among rock arches; The Abyss is a canyon lit only by glowing creatures and your own floodlights; Fire Below breaks through the seabed into basalt and magma. A dashed line on the scene marks where the next zone begins, and the strip at the top names it.

There is no bottom to hit. Below the magma the water keeps going, one new zone every few thousand metres, each one leaning hard on a different system than the zone before it and each a little tougher than the last, so a better refit always has somewhere new to reach. Progress saves automatically in your browser, the rig keeps working while the tab is closed, and there is nothing to install.

No reflexes needed - the rig mines on its own, online and off. Tap UPGRADE to spend salvage on a module (or press 1-5 for the rows of the Rig tab). Open POWER to move reactor pips between Drill, Thrust, Hull and Lumen; each depth wants a different mix. The button on the scene toggles the depth limiter: AUTO parks you at the deepest your hull holds, PUSH dives past it and bleeds integrity for more salvage. REFIT cashes the rig in for permanent Pearls. On a keyboard, Space toggles the limiter and the arrow keys switch tabs.
