To abort early (and painfully), press Alt-Y to crash.

For a debug screen, press Alt-D while playing.

While flying, press Alt-O for a special menu.

For a one-hit kill against many enemies, start the game with the command "WC3 -mitchell". While flying, target an enemy and press Ctrl-W to destroy it. To destroy all enemy ships, press Ctrl-Alt-W.

Note: This trick is known to work against fighters and capital ships, but it may not work on all targets.

Press Ctrl + Alt + S whenever you are watching a movie clip, and the movie will run extremely fast.
