Carrier Command Amiga Cheats

Pause the game and type 'THE BEST IS YET TO BE'. The game restarts
automatically, and  displays  'Cheat Mode Activated' in the message
panel. Now, press the plus key on the numeric keypad. The mantas and
walrus' will be invulnerable except to crashing (low altitude). Or
try surrendering and press the + and - keys to cycle all through all
the objects in the game.
When paused, pressing + and - on the numeric keypad toggles Manta
invincibility: the flying craft are no longer vulnerable to aerial
attack, although collision with large objects is still fatal. Once a
course has been programmed for the carrier, Mantas or Walruses,
engage autopilot and click on pause. To avoid sloggin around inreal
type, you will find that pausing and pressing

1 - Refuels the craft in question.
2 - Replaces lost shielding.
3 - Takes the corresponding craft directly to its destination.
6 - Brings up the programmers' test palette!
7 - Speeds up the game.
9 - Shows the current difficulty level.

A lot in this excellent simulation. PAUSE the game and type
GROW OLD ALONG WITH ME then press + on the numeric keypad for your
mantas and walruses to become shielded. Press - to disable.
