Cargo Drive

Cargo Drive is a browser-based HTML5 physics cargo delivery game where a multi-axle truck carries unanchored freight through rugged wilderness terrain. The real-time center-of-gravity engine shifts dynamically with payload weight — every acceleration, braking, and steering input changes where the load sits in the open cargo bed. Taking a 45-degree hill climb at maximum speed reduces rear-axle traction efficiency by 58.4%, causing wheel spin or engine stall.

The correct hill technique is to build full approach speed on the flat section before the incline begins, then hold or reduce throttle on the slope itself. Mud crossings require steady mid-throttle from entry to exit — stopping mid-crossing sinks the truck past the traction recovery threshold. Hard braking with a loaded cargo bed pitches freight forward; release the throttle gradually over three to four truck lengths before any stop. Truck rollover or total cargo loss triggers a mandatory stage reset with no partial progress saved.
