Build cars, rockets, planes and anything else you can think of, then drive them, fly them and crash them. And the Blue Screen of Death finally does something worth crashing for.

- A new **Parts** folder with 23 parts: boards, metal beams, plates and braces, glass, three sizes of wheel, a seat, a rocket engine, a jet engine, a thruster block, a propeller, wings, left and right tail fins, nose cones, a decoupler, a light and a horn.

- **How to build.txt** at the top of the Parts folder opens in Notepad and walks you through your first car, step by step.

- **No separate tool to learn**: click a part (or drag it out of the folder) and it follows your cursor. Click to place it, Q and E turn it, right-click turns auto-weld off, Delete removes the part under the cursor.

- **You can see what will happen before you click.** The part's own outline follows the cursor: green means it will weld to the parts outlined with it, white means it would be loose.

- **Wheels snap on.** Bring a wheel near your frame and it jumps onto it, on an axle at the gold dot (to the very end of a beam when you're near one). If the frame is lying on the floor it's lifted so the wheels stand on it. Wheels are never welded: a part placed over a wheel becomes its axle instead of locking it.

- **Drive and fly**: D drives right and A drives left, W fires engines, thrusters and propellers, and G separates rocket stages at their decouplers. Wings give lift, fins keep things flying straight, rockets burn fuel and set fire to what's behind them, H honks the horn and F switches a light. Any part's key can be changed (or reversed) on its Properties sheet (Alt+Enter over it).

- **Seats**: drag a person onto a seat to strap them in. A hard enough crash snaps the belt and sends them through the windscreen. F on the seat ejects them.

- **Six example vehicles** to start from or pull apart: Car, Monster truck, Rocket, Two-stage rocket, Glider and Prop plane.

- **Contraptions**: Ctrl+C on any part copies the whole vehicle, with its welds, axles and controls. Ctrl+Shift+S (or "Save contraption…" on a part's Properties) saves it to My Documents → Contraptions, ready to place again.

- Every part has its own pixel art in one shared style: XP-blue bodywork with racing stripes, treaded tyres with chrome rims and hub caps, steel girders and diamond plate, hazard-striped decouplers, white rockets with copper nozzles, a chrome jet with a fan intake, a wooden propeller with red tips, and the FleshOS heart roundel on anything that flies.

- Bodywork sits in front of the wheels like wheel arches, and frames sit behind them so the hubs show, so wheels no longer look stuck through the car.

- Lights have a soft glow and a beam ahead of them.
