Skirmish

Skirmish is a singleplayer game mode in most Command & Conquer games, first introduced in Command & Conquer: Red Alert. It is essentially a multiplayer mode with only one human player facing one or more AI opponents. It is played offline, just like campaign modes.

Do note that Tiberian Twilight skirmishes still require an internet connection to save progress/level-up. If the connection is severed, after the match ends the player is prompted to login. A save is generated at the time of loss of connection and must be loaded by the player and played again to get any XP from that match.

The player is always the "host" and can decide conditions of a skirmish battle by adjusting various options, including: player name, factions, colours, maps, number of AI opponents, AI difficulty levels, starting credits, etc. However, certain options are not available in particular games.

A random map generator was integrated into the skirmish and multiplayer modes of Tiberian Sun, Red Alert 2, and their respective expansions.

In earlier games (or earlier versions of said games), progress of a skirmish could not be saved like campaign missions, but this was later enabled in fan patches.
