Games Like ProjectX

ProjectX is a physics-based extreme sports sandbox from Mash Games, currently focused on mountain biking.

At launch, ProjectX is about riding a mountain bike, learning how it reacts to terrain, finding lines, customizing your setup, and experimenting inside a growing physics sandbox. The goal is not to build a traditional story-driven game or career mode. The goal is to build a responsive, replayable simulation space where the fun comes from movement, mastery, experimentation, and emergent moments.

Right now, mountain biking is the focus because that is where we have found the most fun in our current prototypes. You can ride a bike, explore the available trails, customize your bike and rider, and experience the early foundation of the physics and handling systems we are building.

ProjectX is not intended to be permanently limited to one sport or activity. Over time, we may explore other physics-based sports and playable activities within the same project.

The World We Are Building

We are currently building one medium-sized bike park and discovering how to create that world as development continues. Some parts of the park are already fun to ride, so we would like to begin sharing them with players while we continue working on the rest.

ProjectX is not an open-world game, and we are not working toward making it one. The current world is a focused bike park map designed around a smaller number of carefully built trails.

The riding terrain is authored by hand rather than generated procedurally. Berms, jumps, transitions, and trail sections are shaped deliberately so that even a short run can remain interesting after repeated attempts. Our priority is not the size of the map. It is making the available singletrack feel as good as we can make it.

We are not trying to manufacture a broad open-world adventure. We want learning a trail, discovering faster lines, improving your time, and gaining control over the bike to become an experience of its own.

ProjectX is also not intended to be the most realistic mountain biking simulation possible. We are artists and developers trying to communicate the parts of riding that we find most enjoyable. Physics and realism matter, but they may be interpreted, adjusted, or exaggerated in service of control, expression, and fun. “Sim-cade” may be the closest description of the current approach.

Early Access

This is an Early Access project in the most literal sense. It is unfinished. It will have bugs. It will change. Some systems, trails, and content may be rebuilt, removed, expanded, or replaced as development continues.

If you want a finished, polished, content-complete product, please wait until ProjectX leaves Early Access.

If you want to ride what we are building now, support development, give feedback, and be part of the process while the foundation is still being shaped, we would be grateful to have you along for the ride.

Third-Party Account Required

ProjectX requires a mod.io account and acceptance of the mod.io Terms of Use to play.

ProjectX uses mod.io as part of its foundation for player content, customization, community-driven systems, and future mod support. Because these systems are part of how ProjectX is being built, players are required to create or connect a mod.io account and agree to the mod.io Terms of Use before accessing the game.

Please do not purchase ProjectX if you are not willing to create or connect a mod.io account or agree to the mod.io Terms of Use.
