Grand Truck Simulator: rebuilding the original, one truck at a time

We are recovering and modernizing the game that started the Grand Truck Simulator series. Today, we want to share some of the progress making that return possible.

Where it all began

More than a decade ago, Grand Truck Simulator began a journey that continues with Grand Truck Simulator 2 and the development of Grand Truck Simulator 3. As the series moved forward, however, the original game remained tied to technology from an earlier generation.

Its older Unity foundation made maintenance and updates increasingly difficult. Those limitations prevented the game from evolving for many years.

That is beginning to change. At Pulsar Gamesoft, we have resumed work on the original project, modernizing its systems while protecting what made it distinctive. This is about more than upgrading Unity: we are rebuilding important parts of how the game works.

Bringing the trucks back to the road

One of our main efforts focuses on the vehicles. We are progressively modernizing engines, gearboxes, differentials, and how these systems interact with each truck’s physics.

Several vehicles have already gone through stages of this process, while others still need work. Each requires its own setup and testing. Our aim is not to make every truck feel identical, but to preserve its characteristics while achieving more consistent driving behavior.

Trailers are part of the rebuild too

We are also recovering and refining the original trailers. Recent work includes coupling and uncoupling, wheel physics, mass distribution, braking, and preserving trailer state when a saved game is loaded.

Important improvements have been integrated for one of the trailers used in these tests. This does not mean every trailer has been upgraded or that every test has passed. We are still addressing behavior found during driving tests and preparing the work needed for the rest of the fleet.

These systems are connected: changing physics can affect coupling, brakes, and even where a trailer appears after loading a game. That is why we are moving forward carefully, with incremental verification.

Preserving the spirit of the original

What we have learned from GTS2 and GTS3 helps us tackle challenges that were once much harder to solve. But our goal is not to turn the first Grand Truck Simulator into a different game.

Its trucks, world, and driving style are part of Pulsar Gamesoft’s history and of many players’ memories. We are working with the original project to give it a stronger technical foundation. A full Unity modernization is still a later step: first, we are prioritizing the recovery and validation of trucks and trailers.

When will it be available?

We do not have a release or update date to announce. Driving tests, work on more trailers, and major technical modernization steps are still ahead.

We would rather share verified progress than promise dates we cannot yet guarantee. What we can confirm is that Grand Truck Simulator is back in active development, with tangible improvements to its trucks and trailers.

The story of Grand Truck Simulator is not over. Thank you for being part of it.
