If you meant "download features" or general game capabilities:

: To access mods or version selectors, you often need to add -ui to the game's Launch Options in Steam or create a shortcut with that suffix. This opens a hidden launcher that allows you to select installed mods or game versions. Core Game Features (Current Version)

: You can manually swap version files by navigating to the game folder and renaming the .SkuDef files. For example, renaming CNC3_english_1.9.SkuDef to an older version's name can sometimes trick the launcher into using those settings.

Command & Conquer 3: Tiberium Wars does not have an official built-in "downgrade" feature. However, users often downgrade the game to or 1.08 because later patches (specifically 1.09) significantly altered unit balancing for multiplayer, which some players feel made certain campaign missions much more difficult.

: A popular alternative to a full downgrade is using the "CNC3Original" mod . This mod restores the original 1.0 unit stats and campaign difficulty without requiring you to change the actual game files.
