# Red Planet 4.12

**Red Planet** is the VWE pod-racing game built on the in-house **MUNGA** engine
(Win32 / DirectX 9, `MUNGA_L4` platform layer). The **4.12** line is the
consumer port: a version of Red Planet that can be **sold on Steam** and played
over **internet multiplayer**, without cockpit-pod hardware.

Forked from [RP411](https://gitea.mysticmachines.com/VWE/RP411.git)
(the arcade/cockpit 4.11 line) with full history preserved.

## Goals

1. **Steam distribution** — Steamworks integration, SteamPipe builds, store-ready packaging.
2. **Internet multiplayer** — take the engine's LAN-era WinSock networking online
   (NAT traversal, matchmaking, latency tolerance).
3. **No cockpit required** — keyboard / mouse / gamepad input and on-screen
   replacements for the pod's RIO panel and plasma display, drawing on
   [vRIO](https://gitea.mysticmachines.com/VWE/VRIO.git).
4. **Self-hosted sessions** — in-game race setup/join replacing the operator-driven
   [TeslaConsole](https://gitea.mysticmachines.com/VWE/TeslaSuite.git) flow.

See [docs/RP412-ROADMAP.md](docs/RP412-ROADMAP.md) for the plan and the
Steam-multiplayer logistics.

## Building

Unchanged from 4.11 for now — see [BUILD.md](BUILD.md)
(VS 2005/2008 + DirectX SDK June 2010, `Release|Win32`, output `Release\rpl4opt.exe`).
Toolchain modernization is a roadmap item.
