Miners of Mars: Space Cowboy
A free 3D space mining game you play in the browser. You fly a VTOL ore hauler across a procedurally generated Mars: load osmium out of 7 mines scattered across the shelf, lift injured miners off the rock, and bring crews home to Ferris Station at the end of a shift.
No download, no account, no install. Best played on desktop with a keyboard or a gamepad.
What you actually do
Every job is the same shape and never the same flight: get the ship off the pad, cross a few dozen kilometres of Martian ground, and set down somewhere that was not built for you. Landing is the whole game. The hauler is heavy, Mars has a third of Earth's gravity and almost no air to slow you with, and the pad does not move.
You tilt the lift vector to go anywhere and hold the aft boosters to cover ground — pinned boost empties a full tank in about six minutes, so distance is a decision rather than a cruise setting. On the way down the HUD tells you which of four conditions you are failing: PAD, SINK, LEVEL, DRIFT. Get all four and the skids take it. Miss one and the hull shop takes your money.
Features
A 16-mission campaign
Sixteen authored jobs flown in order, 29,700 credits of work. They start honest — a crew off shift, a load of aggregate, a man hurt underground — and then get strange.
A different Mars every seed
Terrain, craters, erosion and the siting of every mine are generated from a seed you can write down and share. Nothing about the surface is hand-placed.
10 upgrade lines, 26 levels
Auxiliary tanks, booster overhauls, a deeper bay, reinforced skids, a wider approach computer. Fit the ship you want; you cannot afford all of it.
Fly it or hand it over
The autopilot flies the same controls through the same physics and has to meet the same tolerances. It is help, not a teleport — and it tells you why when it refuses.
Get out and walk
Shut down on the paint and step outside. The workshop and the casino out on the shelf are doors you walk through, in a suit, with a storm coming.
Runs in the browser
WebGL and three.js. Nothing to install, nothing to sign up for, and your progress saves to the machine you played it on.
Free, in a browser, no download
The whole game is a web page. There is no launcher, no account and no store: open the game and it generates a world while you read the seed. It needs a WebGL-capable browser — any current Chrome, Firefox, Edge or Safari — and it is genuinely better with a gamepad, because a hover is a small steady correction held for seconds and that is exactly what an on-or-off key cannot express.
New here? The beginner's guide covers the first hour, the controls page lists every keybind, and the landing guide is the one that actually makes you better at it.
