Portal Gateway

Supports portals, that is used for placing workers on places you have visited.

Three upgrades are possible:

• Number of portals
• Portal life length
• Range (how big the portal is)

The portal can be used tactically in 2 ways:

• 1. Extend the range of your primary action circle. If a fountain is just out of reach, place a portal at the edge of your action circle to encompass the fountain.
• 2. When passing by an area with a lot of fountains of your color, you can place a portal there so you can deploy workers at a later time, even when you have left the area.

To place the portal, at least half of it has to be inside your action circle. It will remain in place even when your action circle moves away.

Build cost: 0 (you start with one)

Fun fact: Because of how the formula range works, in theory if all ranged upgrades would fit into the base and wouldn't cost a nearly infinite amount of crystals the range would max after 3197 upgrades at 500 meters.
