Press [~] while playing, then type any of the following codes:
cheat_coal(9999) - Add Coal
cheat_electricity(9999) - Add Electricity
cheat_buildings - Add Buildings
I got these cheats by looking through the Impossible Creatures files
using Find all files including "cheat." and opening those files with
a txt editor looking for anything that looks like a cheat next to that
string. This should work for other games too.
cheat_killself - Blowup all that you have
cheat_buildings - No building restrictions
cheat_rank - ??? (Likely a campaign cheat)
cheat_coal(#) - Gain # coal
cheat electricity(#) - Gain # electricity.
After training a creature with digging abilities,
put it to dig. Then press Esc and save the game. After that, load the
previous saved game. The creature will turn invisible and will be able to
atack too, not like camouflaged creatures, that can't fight while going
unseen. Pretty cool, huh?
