Mud slows non-off-road cars. The water lane (right side) floods non-amphibious cars; use the dry left side. Shoot the red-white targets, red barrels (they explode) and drones for points. Chain hits for a combo up to x5. Drive through the glowing boxes: yellow ammo, red missiles, black bombs, green health, blue nitro, cyan shield, orange new gun (cannon or spread), purple traps (landmines or spike strips, dropped with the bomb button before bombs). Hover cars float over mud, oil and mines and glide off ramps; boats are fast on water and slow on land. Blasts on top of or under a car damage the roof or underside. Try them in Maps: Lakeside Test Area. DERBY: last car running wins; wrecked cars are out; ram and shoot. TOURNAMENT: points for every place over several rounds. Hit the yellow ramp for a jump. Damage shows where you are hit.

Drive point to point across countries. Each leg is a new map. Fuel lasts about 4 km: pull into a service station (green marker on the mini-map), stop, and it refuels and repairs for cash. Earn cash from targets, kills and leg finishes. Out of fuel: a tow truck comes after 3 s, or press RESET (+45 s, -$100). Damage carries over.

Maps are data files (birco-map/1). Set a map's next to another map's id to link them into a run. Anyone can make one in the editor and share the file.

A series of races with the car you picked. Every place scores points (10, 8, 6, 5, 4, 3, 2, 1). Most points after the last round wins the cup. Each race starts with a fresh car.

Load a .glb file (glTF 2.0, up to 15 MB, no Draco compression) to replace this car's look. It is resized to the car's length. Name wheel parts "wheel_FL", "wheel_FR", "wheel_RL", "wheel_RR" so they spin. Handling does not change.
