📄️ Fast Downloads
Fast Downloads (FastDL) mirrors a chosen set of a service's files to a public web location, so game clients can pull large assets — maps, custom content — directly over HTTP instead of through the slower in-game transfer. Source-engine games (CS, Garry's Mod, TF2, HL2DM, …) support this natively and will even decompress .bz2 files automatically.
📄️ Mods
Mods are optional add-ons that you curate on a blueprint and that users can install on their services with one click — typically a server-side plugin or extension. Examples are AMX Mod X for Counter-Strike or Geyser for Minecraft. Unlike updates, several mods can be installed on the same service at once.
