Think Trials but swap the motorbike for a 4x4 truck and strip out the steering wheel entirely. Whether that sounds clever or alarming tells you everything you need to know.

My first reaction to O3DX was genuine confusion, and honestly that is the most interesting thing about it. This is a side-scrolling obstacle racer built on Valve's Source engine where your only inputs are throttle, reverse, and brake. Steering is removed completely. The truck follows a spline-based path automatically, and your job is to manage weight, momentum, and timing to clear physics-driven obstacles, jumps, and pivot ramps across a series of locked, linear levels. That is a genuinely unusual design choice, and it is either going to click with you in the first ten minutes or frustrate you indefinitely. The structure is a three-tier loop per level: finish the course to unlock the next one, then replay it to beat the clock, then go again while also collecting every star scattered along the route. Bonus levels sit behind full star runs from preceding stages, so completionists have a real carrot to chase. The vehicle roster spans classic 4x4 trucks, military off-road rigs, and modern all-terrain vehicles, each with different weight and suspension behaviour that changes how you attack the same obstacles. The cinematic camera system is a genuine highlight - it uses artist-placed spline positions to swing between close-up wheel views and wide canyon shots at exactly the right moments, which gives the whole thing a more polished visual feel than a small indie title from 2016 has any right to expect. Here is where I have to level with you, though. With only a handful of Steam reviews ever recorded and zero critic coverage, the player pool for this one is basically nonexistent. There is no multiplayer of any kind, no online leaderboards worth talking about, and no couch co-op - so my usual tournament-night crowd has nowhere to plug in. Xbox 360 controller support is advertised, but community threads from launch flagged that it was unreliable out of the box for some users, which is a concern. The "self-steering physics obstacle" hook is genuinely creative, but whether the level count justifies the asking price is hard to verify when the community has essentially gone quiet since 2016. Who is this for? Trials fans looking for a slower, more puzzle-y take on the obstacle-course formula might find the throttle-management loop satisfying. Patient solo players who like replaying levels for a faster clean run will get the most out of the star and time-trial systems. Casual groups hoping for a party racing game should look elsewhere entirely - O3DX is a single-player head-scratcher through and through, and its low community footprint means you are mostly on your own if you get stuck.
