Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

eXpanSIM is dynamically evolving. We would like to verify our ideas and take into account feedback from the community before the official release. Early Access gives us a chance to reach true enthusiasts of the genre.”

Approximately how long will this game be in Early Access?

“We are planning to stay in Early Access for one year. The speed of project development depends largely on the engagement of the community and sponsors.”

How is the full version planned to differ from the Early Access version?

“Before leaving Early Access, we will add more vehicles with visual customisation and new real locations. Maybe we will be able to add multiplayer and career mode.”

What is the current state of the Early Access version?

“The current version of the simulator offers realistic vehicle physics and driving in the VR mode. Vehicles and locations listed in the game description below are available. The graphic content is still being enhanced, and the vehicle parameters are constantly tuned. Racing and driving school modes are under construction.”

Will the game be priced differently during and after Early Access?

“During Early Access and after leaving it, the game will be available as Free to Play. The simulator has a built-in store and subscription plans giving access to selected features of the product. The subscription plans and their prices may change.”

How are you planning on involving the Community in your development process?

“We encourage anyone who has the technical knowledge or practical experience to share your thoughts about the simulator. We would like to collect useful information about technical aspects of various types of vehicles on the Steam forums. As game developers, we often do not have access to the data that is available to companies from the automotive industry. We hope that with the active support of the community, we can gather all the technical knowledge that is necessary to model a big collection of vehicles in our simulator accurately.”

Patch update #1: Racing wheels FTW



What's new
  • Added default support for Logitech G29 / G920 and Thrustmaster T500 RS racing wheels
  • Added more details to Track Poznan
  • Reorganized config file structure (separated wheel shape, tire, and brake parameters)
  • Added input signals to the plot list
Physics
  • Improved steering wheel force feedback (self-aligning torque, wheel collision force, and vibration)
  • Tuned vehicle suspension parameters
  • Tuned brake forces
  • Improved tire deflection animation
Bugfixes
  • Fixed objects suddenly spawning in front of you (LOD bias)
  • Track Poznan: removed grass from the asphalt, fixed incorrect physics materials
  • Windridge City: removed terrain protruding from under the asphalt
  • Added map bounds colliders
  • Added minor UI design improvements
Issues
  • Sometimes force feedback is lost when entering VR mode - otherwise, it should work

eXpanSIM entered Early Access



eXpanSIM just recently surfaced on Steam, but the development really started more than a year ago. Thanks to the hard work of the team, our new project is finally ready to be announced.

Our adventure with vehicle simulators began about two years ago when we were contracted to make a new truck driving simulator for Grupa CARGO, the largest driving school in Poland. One of the biggest challenges was understanding all the aspects of realistic vehicle physics and implementing them efficiently. After almost a year of development, our software was officially certified and put into practical use. It is now an important element in the training process of professional drivers.



But what do you do to take a break from such a strenuous project? Of course, you start another one! This is how an innocent exercise intended to learn the new Entity-Component-System (ECS) in Unity 'suddenly' evolved into a new vehicle simulator. Only this time we had proper tools and knowledge of how to do it right from the beginning.

In short, ECS is a new way of writing performant code in Unity. Thanks to ECS-based architecture we can:
  1. Take full advantage of today's multicore processors
  2. Accelerate the computation of vehicle physics and AI
  3. Increase the frequency and precision of vehicle physics simulation



At the current stage of development, our original ECS-based vehicle physics engine is ready to be released. During the next weeks, we will prepare foundations for a research testbed in our simulator. It will be a modern tool for engineers, designers, Artificial Intelligence researchers working on autonomous vehicles and more. We believe that our realistic vehicle physics will help to minimise the gap between experimental results and the real-world performance.



Sounds boring? Then how about racing with autonomous vehicles? We have not forgotten about gamers who play vehicle simulators for fun. With VR technology, we are going to deliver the most realistic experience a game can offer you. It will be possible to use the simulator to learn driving a real car or a truck.

About This Game



eXpanSIM is a universal vehicle simulator that supports VR and lets you:

  • train the technique of driving cars and trucks,
  • test your strength in competitive driving,
  • validate new solutions and conduct experimental research.

eXpanSIM aims to capture the realism of driving cars and trucks of different types. The game offers a range of different locations including urban environments, race tracks, and off-road routes. Driving in VR mode is optional.

The project is powered by an original vehicle physics engine designed for professional applications. It was developed by Raving Bots, a Polish indie studio.

Driving school


Improve your driving skills. Learn the principles of eco-driving and hone your driving technique. A range of specially designed training scenarios will lead you to perfection.

Racing


Prepare yourself for a high realism and an extreme level of difficulty. There will be no driving assistance systems (unless they exist in real vehicles). You've been warned.

Research testbed


Communicate with the simulation using a convenient API. Conduct a series of experiments and collect results easily. eXpanSIM is a modern tool for engineers, designers, Artificial Intelligence researchers working on autonomous vehicles and more.

Vehicles


Currently available vehicles:

  • a city car,
  • a race car,
  • a pickup,
  • a limousine,
  • a van,
  • a city bus,
  • an intercity bus,
  • a lorry (with a semitrailer or a tanker),
  • an off-road truck,
  • a fire truck.

Vehicle models have right-hand and left-hand traffic variants as well. We are constantly expanding the collection of available vehicles. In the near future, the drones will be added.

Equipment


To fully experience the potential of the simulator, it is recommended to use a steering wheel with pedals. The game supports popular VR equipment such as HTC Vive and Oculus Rift.

Work in progress


The project is currently in closed beta testing. Contact us if you would like to get access.
