Screenshots & showcase GIF

After cloning, run sync-from-projects.ps1 to copy wasm builds from your local *web port projects on the Desktop.

Quick start (local)

cd buildgit

# 1. Copy wasm/js/data from sibling *web projects (Desktop)
powershell -File sync-from-projects.ps1
powershell -File install-usergrp.ps1

# 2. Start unified server (port 8760)
powershell -File start-servers.ps1
# or: python serve.py

Open http://127.0.0.1:8760/ — select your GRP or game folder, then PLAY.

Hard-refresh after rebuilds: Ctrl+F5.

Supported games

Blood, Lenin: First Blood, Redneck Rampage, Duke Nukem 3D (+ DLC), Shadow Warrior (+ addons), NAM, WW2 GI, Powerslave, TekWar, Witchaven I/II, Liquidator, Plunder & Pillage, Quest TCs, and more — see the launcher grid.

Deploy

Upload the whole folder to static hosting (same structure as the live site). Runtime binaries must be present in each ####-slug/ directory.

powershell -File scripts\prepare-unplugged.ps1   # verify Unplugged/ layout

Unplugged (no GRP check): /Unplugged/ — same game paths, ../8766-blood/run.html etc.

Build details

See BUILD.md for the full port matrix, Emscripten commands, and Duke DLC pipeline.

License

Engine source lives in separate *web repositories (NBlood, EDuke32, Rednukem, etc.). This repo contains only the showcase shell — HTML, scripts, and launcher assets. Game data remains the property of their respective rights holders.
