Человеки: Знакомство с предками чит-файл №1

Load the game as usual and don't do anything until the highscore screen
appears. Type 'COMMANDER' and then press the fire button. After a few
moments press F10. If your ship flickers you are now invulnerable, and
have infinite expansions and smart bombs.
                               
F1-F5 = Other Six Levels of 'expansion' (you can still capture the capsules)
F8 = Advance a level (There are three)
F10 = Turn cheat mode on/off

You cannot get a high score with the cheat mode on.
