CHEATS:
Press "T" during gameplay and enter the cheat code followed by RETURN:

"GODNESS" or "1GODNESS" = more money
"DECADES" or "2DECADES" = upgrade factories to max tech level
"ABLAZEW" or "3ABLAZEW" = win the mission
"LOOSING" or "4LOOSING" = lose the mission (!)
"TICKING" or "5TICKING" = extra time in timed missions (repeatable)
"WARFOGY" or "6WARFOGY" = remove fog of war, reveal entire map

TIPS:
Once you can afford a spaceport, build it and use it to order a Nuclear
or Napalm strike. Select it (blue crosshair appears) and pick a target.
Do NOT confirm with left mouse button — cancel with right mouse button
instead! You get your credits back but can still use the blue crosshair
to select a target and launch it for free with left mouse button.

Destroy an empty oil tower with the "K" key (followed by right and left
mouse button). You can then build a new oil tower on that source and
extract 3-4 more tanker loads. This can be repeated 2-3 times before
the source dries up permanently.

When sending a group of mixed units into enemy territory, hold the CTRL
key when selecting the destination. This auto-adjusts all unit speeds
so no unit moves faster than the slowest one.
