Gold bars

Gold bars are one of the two forms of payment. They are worth less than iron bars. 10 gold bars=1 iron bar.

In the beginning, you work for the gold factory. When you work for the gold factory you receive 1 gold bar a second. When you work you can also make the boss happier, either by killing rats or ciphering some codes.

After a little bit of time you can choose to buy the gold factory for 5000 gold bars. This unlocks the ability to buy mining machines to get more gold bars a second. When buying the factory you automaticly get 30 mining machines with it. One thing to keep in mind when you are about to buy the gold factory is that it disables the function to make your boss happy and receive bonuses.

You can also get gold from killing enemies, the enemy's max HP equals to the gold bars you get after killing it. For example, killing the rat that has 77 HP will give exactly 77 gold bars if you kill it.
