Legacy of the Ark: Beneath the Broken Sky

An idle survival epic that respects your time. Progress keeps ticking while you're away — and every return brings your camp a little further from the wreck and closer to the truth beneath the world.

Start from nothing

One survivor, one broken hull, and your own two hands. Click to gather until you can wake the others.

One mechanic at a time

Gather → rescue → assign → upgrade → expedition → settle → research → descend. Nothing is dumped on you at once.

Consistent time

Online and offline run the exact same simulation. Come back to real progress, never a punishment.

A descent with an ending

Beyond the surface lies the Deep Ark and the Anchor Test — a prestige loop that reaches for a true ending.

Layer after interlocking layer — each one earned, each one deepening the last.

Gather by Hand

Click water, food, and material to build your first stockpile. Tools and skills make every click and every survivor count.

Core loop

Survivors

Search the wreck for cryopods. Assign the people you find to gather automatically — even while you're gone.

Automation

Expeditions

Send parties out for hours to haul back resources, new survivors, and the first ground worth settling.

Exploration

Settlement

Break camp to bank everything into a permanent home. Assign workers to six categories and build 60 facilities.

Meta layer

Research

Turn survivors into researchers. Points across six disciplines unlock the settlement upgrades that reshape your economy.

Progression

Deep Exploration

Chart a 100-node map beneath the world, node by node — caches, evidence, Watchers, and a hatch of Ark alloy.

The descent

The First Wave

Evidence of a catastrophe that aged the ground unevenly. Claim each stage you uncover for a burst of everything.

Mystery

The Deep Ark

Sacrifice survivors through sixteen milestones toward the Anchor Test — the machine bending the sky.

Endgame

Prestige & Memory

The Anchor Test resets the run for Memories — permanent upgrades and a Time Stability meter reaching for the true ending.

Prestige

Events

Story moments that pause the world and ask something of your camp — a loss, a windfall, a warning from the reeds.

Narrative

Ark Fall

Salvage crashes down periodically. Click it for resources, research, cryo-pod survivors, or a shove to your expedition.

Surprise

Offline Progress

Your camp works while you sleep. The same tick math replays your time away — capped, consistent, and fair.

Idle-friendly

This is where every game of Beneath the Broken Sky begins — by hand, from nothing.

From a click to a colony

Gather 30 material to search the wreck and wake your first survivor. In the full game, that survivor gathers for you automatically — then the loop opens into tools, expeditions, settlements, research, and the long descent below.

This teaser runs a tiny slice of the real economy. The rest is on Steam.

Nine locations form the forward march — each one settled, abandoned, and left behind as you press on toward the Deep Gate. Drag to explore.

Site 09 · The Descent

Deep Gate

A light thread of mystery, uncovered at your own pace and kept in a Story Archive you can re-read any time. The survivors you meet came down from other pieces of the Ark — their stories are their own.

Long before

The First Wave

Something passed through this land and aged it unevenly — a pressed ring of dead grass, clocks that no longer agree. The evidence is everywhere, once you learn to read it.

Now · The surface

A crash site, and a hand

You wake at one fallen piece of the Ark. Gather, rescue, and rebuild across nine sites until you find the Deep Gate — the way down.

Below

The descent

An underland older than the Ark, shaped by patient hands and shadowed by the Watchers, who keep a tally of your party — and add one more.

At the bottom

The Deep Ark & the Anchor Test

A machine seamed into ancient bedrock, bending the sky. The Anchor Test resets everything you've built — and each attempt nudges Time Stability toward a true ending.
