How FastDL Works On Your Nuclear Dawn Server

FastDL sends your custom maps, models, materials and sounds to players over the web, which is much faster than downloading them from the game server. It's built in and needs no setup.

How It Works

Every time your server starts, it publishes your server's maps and content files to its own FastDL web server and points players at it. Just upload your files and restart.

FolderFile types
nucleardawn/maps.bsp, .nav
nucleardawn/materials.vmt, .vtf
nucleardawn/models.mdl, .vvd, .vtx, .phy, .ani
nucleardawn/sound.wav, .mp3
nucleardawn/particles.pcf
nucleardawn/resource.res, .ttf

Compressed copies (the same name ending in .bz2) are served too, if you upload them next to the originals.

To host the files on your own web server instead, set a download redirect.
