MarsRover Mine, Build, Breathe

Take the air from 0.0% to 21%.

GET IT ONGoogle Play Coming soon to theApp Store

You land on Mars with a bad drill, a small battery and one job: make the air breathable. The atmosphere starts at 0.0% oxygen. The run ends — as a win — the moment it reaches 21%, which is Earth's. That is the only ending there is. Everything else you do on this planet is in service of that one number.

What you'll be doing

  • ▲ Mine the surface — seven metals, two rare-earth patches and radioactive shards, all cut by hand.
  • ▲ Build the atmosphere — four oxygen plants, each sited on the exact ground it belongs on.
  • ▲ Clear the radiation — plant mushrooms and watch a contamination zone leave the map for good.
  • ▲ Upgrade everything — battery, engine, drill and protection, five parts each, all paid in ore.
  • ▲ Haul it home — hitch trailers nose to tail and trade top speed for capacity.
  • ▲ Generate your own charge — lay a solar farm out on a lattice; power is never bought.
  • ▲ Take thirteen contracts — all optional, all watching from the moment you land.

Mine the surface

Tap to drive, tap a deposit to cut it. There is no auto-collect and nothing is picked up by being driven over, so what comes home is what you chose to take. Price and scarcity run opposite ways, and the rare species are weighted towards the outer map — so earning well means driving further than is comfortable on the battery you own.

Build the atmosphere

Bore for water ice and cap the strike with a gasifier. Find an oxygen pocket and stand a dispenser on it. Grow mushrooms on radioactive shards. The ladder runs the useful way round: the harder a plant is to site, the better it pays for what it cost. None of them is bought with money — like the rover's own parts, they are built at a workbench out of what you dug up, so what a machine really costs is how far out you had to drive to find its ingredients.

Clear the radiation

Roughly a sixth of the surface is contaminated ground that takes 2 hull a second out of 50 — and the armour shelf does not help, because the counter is a lead shield. Crossing the widest zone very nearly kills you. But a zone is not permanent: plant a mushroom and two minutes later its mycelium takes the contamination out of a wide patch round it, for good. Enough of them and the zone is gone from the map — the stain, the warning stakes and the hull cost with it.

Lose the rover, not the run

A flat battery or a broken hull costs you the machine, not the expedition. A new one lands free at the pad — you lose the hold and the parts you built, and any trailer it was pulling is left standing where it died for you to drive back out to. Your credits, contracts, plants, solar farm and everything in the store room belong to the run.

Drill, craft, tow, terraform — and drive home before the battery goes.

Also in the box

  • ▲ Thirteen optional contracts — all of them watching from the moment you land; there is nothing to sign up for.
  • ▲ Dynamite — for boulders that are in the way, and for mistakes you will make once.
  • ▲ Seeded maps — procedurally generated from a seed you can type in, so a map you liked can be played again.
  • ▲ One expedition, saved as you play — close the app mid-drive and CONTINUE picks it up parked where you left it.
  • ▲ Drawn procedurally — every visual in the world is generated, not painted.

What it doesn't do

  • ▲ No in-app purchases — nothing in the game is for sale, and there is no currency you can buy.
  • ▲ No accounts, no multiplayer, no analytics — there is nothing to sign in to and nothing that watches you play.
  • ▲ No energy timers — nothing waits on a clock you can pay to skip.
  • ▲ Plays fully offline — the only thing that ever touches the network is an optional rewarded video: one that limps a dead rover back onto its wheels, one that ships in a unit of ore. With no connection those buttons simply go dead and the whole game still finishes.

Private by design

MarsRover collects nothing — not even analytics. There are no accounts, no remote database and no server for your expedition to be sent to. Your save, your seed and your progress are stored only on your device. The single third-party component in the app is Google AdMob, and it is reached only in the moment you choose to watch a rewarded video.

Made for

Anyone who likes mining, crafting and survival sandboxes with a real ending — and anyone who wants a game that finishes on a plane, in a tunnel, or anywhere else with no signal. Bring a battery.
