Poly Bridge 3

Poly Bridge 3 – A Fresh Take on Creative Bridge Engineering

Poly Bridge 3 invites you into a world where every bridge is a puzzle waiting to be solved. Whether you enjoy logical challenges or simply love experimenting, this game turns engineering into an addictive and surprisingly relaxing experience. From simple crossings to outrageous constructions that look like they shouldn’t work—but somehow do—you’ll constantly find new ways to guide vehicles safely across the map.

Expansive Campaign Mode

The latest installment introduces a sprawling open-world campaign that spans multiple regions, each packed with new challenges. With more than a hundred handcrafted stages, you’ll encounter everything from high-flying jumps to complex hydraulic systems and classic bridge designs. Soar between towers in Vaulted Towers, wrestle with moving parts in Bifrost Arc, and tackle dozens of other inventive scenarios designed to keep you experimenting for hours.

Sandbox – Your Engineering Playground

If you prefer limitless creativity, Sandbox mode gives you the freedom to construct whatever wild ideas come to mind. Build your dream level, tweak every detail, and then upload it to the Steam Workshop. Friends and players around the world can try your creations, rate them, and share their own. It’s the perfect place to test your boldest concepts without campaign restrictions.

Accurate, Reliable Physics

Poly Bridge 3 runs on a physics engine built specifically for the series. Every beam, cable, and joint behaves exactly the way you expect—no strange surprises, just consistent, realistic results. When your bridge holds under extreme pressure, you’ll know it succeeded because you designed it well.

Personalization & Creative Tools

Mod Support

Mods let you tailor the game to your style. Adjust mechanics, introduce new vehicles or building materials, fine-tune the interface, or translate the experience into your language. You have full control over how simple or complex your world becomes.

Decorative Objects

Give your levels some personality with a huge selection of decorative assets. Basic props like rocks and cones are available, but each world also brings its own themed items. Whether you're aiming for realism or just having fun, you can build environments that match your imagination.

Community Creations

Create custom vehicles, ships, planes, and textured objects to spice up your Workshop levels. Share your designs with other players or download their contributions to enhance your own builds. The community continuously expands what's possible.

A Toolkit Loaded With New Possibilities

Construction Zones

Ready for a tougher challenge? Some levels now limit where you can build, forcing you to think more strategically. You can also alter the paths taken by planes and boats, adding another layer of planning and experimentation.

Source Materials

Levels can now include placed materials or objects right from the start. Use them as part of your design… or work around them if they get in your way. Either choice opens up more inventive approaches.

New Structural Material: Supports

When spanning long distances, you’ll appreciate the new support material. It may cost more, but it dramatically strengthens key sections of your bridges and helps distribute weight where it matters most.
