Regarding the Cheats & Hints.
While in-game, you have the following options available:
Hit F12, this brings up the in-game cheat menu. The cheats may be left-click selected from the menu, or simply typed manually while in game.
If the cheat menu is not in English and appears to be in an Eastern European Slavic language, here is the translation:
CTRL + A ----- Automatically succeed the entire current mission
CTRL + ALT + A ----- Automatically succeed the current phase of the mission (missions have multiple phases)
CTRL + F ----- Automatically fail the mission
To exit the cheat menu, you can hit F12 again or simply click on the last option in the menu.
