3.0: FleshOS Service Pack 3, Welcome to FleshOS (October 2026)

Fleshy shows you around, everything you break pays megabytes, the FleshOS Store sells new toys, hats and whole new operating systems, and every example vehicle now looks like the real thing.

Fleshy, your FleshOS assistant

- **Fleshy** (a paperclip made of flesh) lives in the corner of the desktop and replaces the tour at startup.
- **The desktop starts with people on it**: Kevin, two friends, a crate and a baseball bat.
- **A quick start**: ten short goals, with an arrow pointing at the folder to open and the thing to click glowing inside it (or on the taskbar). Each one pays MB, and "I know what I'm doing" skips it:
1. Throw Kevin (the Drag tool).
2. **Spawn new people**: Props → Humans, or the little person on the taskbar.
3. Fire a gun.
4. **Use a tool**: set someone alight with the Lighter. Every other tool is in the Start menu.
5. Stick C4 on someone and press G.
6. Use a power.
7. **Pour water**: liquids are real fluids, and people swim in them.
8. **Pour lava into the water**: they make rock you can drag around.
9. **Draw in Paint**: what you draw is solid. Pick Stone (or wood, ice, spikes...) and draw a platform.
10. Build Kevin a car and drive it.
- Afterwards Fleshy points out things you haven't tried yet (at most one every few minutes), tells you when you can afford something new, and reacts to the big moments. Right-click him to hide him, or to start the quick start again. He's in Control Panel → Display too.

Megabytes (MB)

- **Everything you break pays MB**: kills (several in a row pay up to four times as much), lost limbs, explosions and nukes, every achievement, and task stars. The amount floats up from where it happened.
- A daily bonus when you come back the next day.
- Your MB are in the tray. Click them to open the Store.

The FleshOS Store

In the Start menu, or click the MB in the tray. It only sells new things: nothing that was free is locked.
- **Toys and weapons**: a bowling ball, a giant rubber duck, a spiked club, an anvil, a pipe bomb, mega dynamite, a piano, a 900 kg wrecking ball and a **cannon** that fires iron cannonballs.
- **Hats**: a party hat, chef hat, hard hat, top hat, cowboy hat, propeller beanie, viking helmet and crown. Hats you own are in Props → Humans: click one, then click someone. New people sometimes come wearing one. A hard knock, or losing their head, sends the hat flying.
- **Fleshy's wardrobe**: a party hat, shades, a top hat, a headset and a crown.
- **Wallpapers**: Sunset Ridge, Snowfield, Red Planet, Midnight and Vaporwave.

New operating systems

The Store's biggest items. Each one reskins the whole desktop, with its own wallpaper, boot screen, startup sound and its own disaster in Powers. Switch any time in the Store or in Control Panel → Display.
- **FleshOS 98**: grey bevelled windows on a teal desktop. Its disaster, **Illegal Operation**, rains error windows down on everyone.
- **Pear OS X**: brushed metal, traffic-light window buttons, a menu bar along the top and a dock. Its disaster, the **Spinning Beach Ball**, is two and a half metres across and rolls over everything.
- **Flinux**: dark panels, a terminal and Gibs the penguin. Its disaster, **sudo rm -rf**, types the command and deletes everyone, one line at a time.

Faster on slower computers

- **Performance mode** (Control Panel → Display): fewer particles, a simpler wallpaper and at most 100 people. The gore and the physics are exactly the same. If your first seconds run under 30 fps, Fleshy offers to switch it on.
- When the graphics card is the bottleneck, FleshOS now notices and simplifies the wallpaper first.
- The wallpaper's clouds cost less to draw (same look).

Vehicles that look like vehicles

Every example vehicle was rebuilt to look like the real thing, and every piece it's made of is in the Parts folder, so you can build them yourself.
- **Car**: a 90s muscle car (a convertible, so you can see the driver), with racing stripes, a hood scoop, a spoiler and sport wheels in its wheel arches.
- **Monster truck**: an orange open-cab pickup with flames and a roll cage, on monster tyres.
- **Rocket**: a moon rocket with the black-and-white roll pattern, a pointed nose and a fin either side.
- **Two-stage rocket**: the first stage, a decoupler, then a second stage topped by a crew capsule with its escape tower.
- **Glider**: a sailplane with a bubble canopy.
- **Prop plane**: a yellow taildragger with an engine cowling, an open cockpit, a landing strut and a tail wheel.
- **14 new parts** under a new "Bodies and shells" heading in Parts: muscle car body, monster truck body, rocket body, short rocket body, rocket nose, crew capsule, glider fuselage, plane fuselage, windshield and spoiler, plus a sport wheel, a tail wheel, a landing strut and a low bucket seat. Car bodies sit behind their wheels, so the wheels show in the arches.

Fixes

- Limbs cut off by spiky paint, dissolved in acid or burnt off in lava no longer crash the game.
- A person dragging a friend to safety no longer crashes when the limb they're holding comes off.
- Spawning hundreds of people no longer breaks the game: there's now a limit of 200 people on screen, and past it the oldest one makes room.
- Resizing the window while someone was in pieces no longer crashes.
