Crack comes from the crackle sound you get when smoking if you use baking soda to make the freebase. I use ammonia. Nowadays they just use the name crack for freebase cocaine, which isn’t really accurate. Where I live we just call it smoking coke because almost everybody uses ammonia, and most people don’t buy freebase directly.
So to be accurate we should call it “freebase cocaine” and not “crack”.
Dungeon Keeper
It’s a dungeon management game from '97. You are an evil Keeper and control a dungeon where you need to build rooms and train your creatures to attack (or defend from) the good guys.
Nowadays people play KeeperFX which is the opensource remake.
