Ever wanted more workers? Thought 500 wasn't enough? Well, your prayers have been answered, with the new Orbital Habitats you can get up to 1,000 workers!

There are two different Orbital Habitats, the first one is simply called an Orbital Habitat, you can build it once you get into the second age at a price of 100,000 gold and iron. The second one is called the Deep Space Colony and is only buildable in the third age. It costs twice as much as the Orbital Habitat. Each adds to your worker cap by 250.

But those workers don't come cheap! In the second age workers cost 250 food, and in the third age a staggaring 1,000 food each. So save up your food and enjoy the ride.
