Here are some cheats and tips for the game A-10 Tank Killer.
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.
