✨ Features

A four wheeler for Valheim: a rugged all-terrain quad for you and a friend, driven by a surtling core's fire. Fast over meadows and hills, with headlights for the night, a rack for your gear and colours to choose from.

Riding it

• Build it with the hammer on dry land, near a workbench: 10 Fine Wood, 10 Iron, 2 Surtling Cores and 8 Leather Scraps.
• Press E on its seat and you climb on and take the handlebars.
• Hold W to go, Shift+W for full speed, S to brake (and back up once stopped); let go and it coasts to a stop. A and D steer.
• It steers like a car: a tight circle at a crawl, a wide one at speed, and it holds its line in a turn instead of sliding.
• Its springs soak up bumps and it stays on the ground over rough country. Deep water stalls it and it floats.
• Jump or E gets you off. Leave it on a slope and it stays where you left it. If it ends up on its side, E on it stands it back on its wheels.
• Run into an enemy at speed and it takes blunt damage (more the faster you go: 90 at 12 m/s, 250 at full speed) and is knocked away, and you lose a little speed. Players and tamed animals are never hurt.
• A gauge at the bottom right shows your speed and what you are asking for, as on the Jet Ski.
• The hammer takes it apart again (not while someone is on it).

Room for two, and their things

• A passenger seat behind the rider (E on the back of the seat).
• A rack at the back holds 8 stacks: E on it. If the four wheeler breaks, what is in it drops in a cargo crate.

The look and the sound

• Sculpted red bodywork with cream rally stripes and curved fenders, a chrome tube bumper and racks front and back, A-arm suspension with coil-over shocks, a finned engine and chrome exhaust, floorboards, a long leather seat, mirrors and handlebars that turn as you steer, and fat chevron-tread tyres on silver rims.
• Two headlights and two tail lights: they come on at night (and in caves) while someone rides it, and the tail lights glow brighter when you brake.
• Paint it: E on the hood gives the next colour (red, blue, green, yellow, black, cream, orange). Everyone sees it.
• A one-cylinder engine that climbs through four gears as you speed up, tyre squeal in hard corners, a thump and a burst of dust when you land a jump, the sound of tyres on the ground, and dust kicked up from each wheel, coloured to the ground you are on: brown earth, pale sand on the plains, white snow in the mountains, grey ash.

Everyone in the world needs it installed.

📜 Recent changes

• 0.1.1 You ride it properly now: leaning over the bars with both hands on the grips (they follow the bars as they turn) and your boots on the floorboards, your head turning where you steer and bobbing over rough ground; a passenger behind holds on round your waist (or rests their hands on the seat when you are alone). Everyone sees it. Plus: the front wheel can no longer get swallowed by a steep slope (the wheels' ground check starts above the suspension and rolls over a rise), a stuck rider gets a small hop free, E on one on its side stands it up, an engine that climbs through four gears, tyre squeal in hard corners and a thump and dust burst on landing, a sculpted new model, and a smaller test-command surface (atv).
• 0.1.0 First release: a four wheeler built with the hammer on dry land. W go, Shift+W full speed, S brake and reverse, A and D steer, E on the seat to climb on, Jump or E to get off. Springs on each wheel, a turning circle that opens up with speed (it holds its line, it doesn't slide), a passenger seat, a rack that holds 8 stacks, headlights and tail lights at night, a gauge at the bottom right, an engine sound, tyre sound and dust coloured to the ground, paint (E on the hood), and E on a flipped one stands it back on its wheels. In your language: Russian, German, Chinese, Portuguese, Spanish, French, Polish and Turkish (translated by AI; corrections welcome).
