Things You'll Need
Instructions
Insert your Starcraft CD-ROM into your computer. Click "Play" to load the game's main menu.
Select the type of game you want to play. (This applies only to people who have both Starcraft and the expansion pack, Brood War, installed on the same computer.) Click "Starcraft" to play a two-player game using the original game. Click "Starcraft: Brood War" to play a two-player game using the expansion pack.
Click "Multiplayer." From the menu that appears, click "Battle.net."
Select the "Create Game" option if you want to set up a new game to play. You can choose what map the game is played on and specify the rules, including how long the game will last. When a second player joins your game, click "Start Game" to play.
Click "Join Game" to join a game someone else has set up. Browse through the list of available "lobbies" on the left side of the screen until you find the one you want to play. The lobby information will contain the size of the game and what map the game is using. Once you join the lobby, wait for whoever created the specific game to click "Start Game." The main game will then load.
