Patch (content)

Content patches are patches that expand upon the content of an existing game, by adding or unlocking additional scenes, interactions, etc. Separately purchased content patches are called DLC. Patches that are included for free that include content are often also called content updates. Patches that include material not suitable for regular distribution due to sexual or otherwise explicit content are called 18+ Patches. Content patches that are not official or are consumer made are called Mods. Significant content updates may also be called expansions, add-ons, or (again) DLC.
