About This Game

Design it. Test it. See what fails first.

FEAT is a structural engineering simulator. You draw the structure, pick a material and cross-section for every member, and press Test. Then a real finite-element solver takes over: trucks cross your bridge, snow piles onto your roof, wind hits your tower and a crowd fills your grandstand.

When the load is too much, FEAT doesn't just say "fail". It marks the first member that gave way, shows whether it buckled or broke, and plays out the collapse in full dynamics. Change one thing and run the same test again.

Much more than bridges

• Catch a rocket. A booster flies back from launch and settles onto your tower's arms: 650 kN that your design has to carry.
  
• Fill a stadium. Load a temporary grandstand row by row with a crowd, or hold up a Big Air ramp for snowboarders in snow and wind.
  
• Real-world collections. 21 structures from industry, energy, the city and leisure: a Goliath gantry crane, a bucket-wheel excavator, an airship hangar, a Ferris wheel and more.
  
• Roller coasters. 10 famous rides. The track is fixed; you engineer everything that holds it up. In the dips, the train presses several times harder than standing still.
  
• Engineering heritage. 20 historic structures on a globe, from the Forth Bridge and the Eiffel Tower to Tower Bridge and other movable bridges that open for passing ships.
  
• Bridge campaign. 7 contracts beyond trusses: beams, prestressed concrete, arches, and cable-stayed, extradosed, suspension and stress-ribbon bridges.

From student to engineer

You start as an engineering student. 40 contracts across four worlds (Valley, Quarry, Coast and Alpine Passes) take you through truss bridges, snow-loaded roofs, towers in storms and cranes, all the way to the title of Engineer.

If your structure survives, the contract is yours. Three stars go to designs that are also cheap, light and make good use of every member. An early version of the career studio lets you earn fees, fund materials research and buy licences for cranes and roller coasters.

Failure you can explain

Choose steel, timber, concrete, reinforced concrete or steel cable. Slender bars buckle, steel yields, timber snaps in tension, and a cable can't push. Cross-section and length change every result.


The simulation is fully deterministic. The same design under the same load gives the same result, bit for bit: same failure, same moment, same place. That's what makes every star fair.

Sandbox and level editor

Build freely in the sandbox, design your own levels in the level editor, or test one change at a time in the bridge lab.

Made by an engineer

FEAT is made by Owlnut, a one-person studio run by a civil engineer who started the project about ten years ago and came back to finish it.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

FEAT's music and sound effects were generated with ElevenLabs AI tools, then selected and edited by the developer. Some ground and prop textures were generated with an AI image model from the developer's own prompts. The in-game texts and this store page were written with the help of AI language models and reviewed by the developer; the German, Chinese, Portuguese and Spanish translations were produced with AI. The 3D models and scenery are procedural geometry built by code written with AI coding assistance. Nothing is generated by AI while you play.
