Race for the Galaxy: New Worlds Promo is a set of 6 new start worlds for use with Race for the Galaxy.
Star Nomad Raiders
Industrial Robots
Galactic Trade Emissaries
Terraforming Colonists
Abandoned Mine Squatters
Gateway Station
These six new worlds can be added to the base game and any expansions, using the start rule from Rebel vs. Imperium:
Separate the start worlds by number into odd (red) and even (blue) groups. Shuffle and deal two start worlds, one from each group, to each player. Shuffle the remaining start worlds with the game cards and deal six to each player. Each player examines all eight cards (and any expansion goals in play) before discarding one of his two dealt start worlds and two of his six game cards. Players then reveal their start worlds and begin play.
