There is a large selection of Assets (Textures, Models, Sounds, ect) available to use on sbox.game, and you can use them without needing to think about downloading the files/mounting the content/ect.

The mount system is extensible - anyone can write a mount to add support for a new game or engine and contribute it to s&box via pull request. A mount detects a game's install directory via Steam, scans its files, and converts assets into s&box compatible assets, all at runtime.

s&box provides several ways to play sounds in code. You can fire-and-forget a sound at a world position, control it via a SoundHandle, attach it to a GameObject, or use scene components entirely.

Components can contain RPCs. An RPC is a function that when called, is called remotely too.

s&box has a full audio system including 2D/3D sound playback, voice chat, positional audio, an audio effects pipeline, and lip sync support.
