The vehicle building sandbox game TrailMakers, from the developers at Flashbulb Games, is available now on Steam Early Access. A Preview Program version of the game will release on Xbox One later this year.

The TrailMakers Early Access Launch Trailer down below shows off a few of the millions of combinations you can snap together to create land and air vehicles that you can ride around a massive world in the single player Survival Mode or the four player Creative Mode. You'll have to put thought into your vehicles, though, because the TrailMakers engine takes physics into account, so you can't just strap your biggest rocket to your tiny car and think it'll work. That's one of the things we liked about the game when we got to take a look at it at PAX last year.

No word on when the game will come to full release, but Early Access will be available for those looking to get in on the action while Flashbulb looks to work out the kinks. You can find TrailMakers on Steam for a regular price of $19.99. It's on sale right now for $17.99.
