The factory is the the place to produce steel. Making steel at the factory is free, but takes time. The more often you log in, the more steel you can produce by using the shorter-time furnaces. You can also increase the amounts of steel you get by upgrading the factory.
There are 4 types of furnaces, each takes a certain amount of time to finish it's work and manufactures an amount of steel based on that time as follows:
|Furnace||Base Steel Amount||Completion Time||Collect Now Cost|
Factory Upgrades Edit
Each factory upgrade increases the amount of steel manufactured by each furnace, making it worthwhile in the long term to upgrade it.
|Building Level||Upgrade Price||Upgrade Time||Manufacturing Bonus|
|5||Max Level||Max Level||100|
