Notice:

You must have Physics, Society and Engineering research points for the fast research cheat to work.

For god mode to work you must have at least 1 of the 6 ships you start the game with.

God mode cheat was replaced with Add 100 Health, The way the Add health work is that you hover over your ship unit in a fight to show how much health the unit has left then press the hotkey to activate the add health cheat and that unit will get a 100 health added.
