The Replicants are starting to adjust to a solar system devoid of organic life. It was chaos at first, but, for the most part, the mega hives a have started to create some stability. The United Sol Colonies, or U.S.C. for short (who this expansion is focused on), are doing their part to bring structure (or structures =P) to the system. They are currently building a network of space stations that all Replicants may have access to, provided they follow a few simple rules:

No fighting on the space stations.
Use the rooms you need to and move on, so others may use them too.
Help build additions to the stations you visit.
Everyone must spend their own resources to activate functions they wish to use.
Stay out of other hives lockers.

In the U.S.C. Expansion you will pick your favorite hive and join the effort to make the system a better place for all Replicants.

Game play, for the most part, is similar to the core game (which is required to play the expansion.)

Like in the core game, you will deal out a resource grid each round, and place your drones to collect resources. But between those two phases, you now have a Station phase. During the Station phase, you will get to move your two personnel around the station to access the functions of the different rooms. Room functions consist of things like: build new rooms, resource discounts when leveling up new replicants, buying points, and more.

After the Drone phase, you still spend the resources you produced or gained to level up your Replicants. However, instead of discarding any unused resources from your hand at the end of the round, you now send them off to your locker on the space station. Once resources are in your locker, you may not use them for leveling up your replicants, but they can be used for activating any functions on the station.
