Abort bad mission:
------------------
The game normally disables the [Ctrl] + [Alt] + [Delete]
warm boot combination. However, If a mission ends badly
and you wish to stop the game from saving that result,
press [Ctrl] + [Alt] + [Delete] during the brief period
of time when the game loads the next part of the program.
The aborted mission will not be on file when the game is
restarted.
