What is the 'Buy Now' button when upgrading a building?
Need something done right now? When upgrading, building, researching, or training, just click 'Buy Now.' Your project will be completed instantly!
This is called Instant Build. The Platinum price of an Instant Build is based on the time required to complete the project, and how many resources you would need.
If you have any resources on hand, we'll use those first. If you don't have enough resources to finish the job, we'll convert some of your Platinum into resources instantly.
You can even use Instant Build while building or researching something else! With Instant Build, your base is never stuck!
