Players command alien races with unique powers in this space conquest game. Each turn, one player attacks another's planet through hyperspace, with both sides recruiting allies and playing cards. Victory requires establishing five colonies on opponents' planets using combat, strategy, and shifting alliances. Multiple players can achieve joint victory through diplomatic cooperation.

On Your Turn

What you can do during your turn.

2
Note timing

6
Draw destiny
Draw the top card of the destiny deck to determine your opponent
7
Follow card instructions
The destiny card determines which player you encounter
8

If you draw your own color, either target a foreign colony on your home planets or discard and draw again
9
Reclaim empty home planet
If you draw your own color and have an empty home planet, you may automatically re-establish a colony there with up to four ships
10
Redraw conditions
Discard and draw again if the indicated player has no home colonies or if you already have colonies on all their planets
11
Reshuffle destiny
If only one card remains in the destiny deck, shuffle it with the discard pile to form a new deck
12
Choose target planet
Point the hyperspace gate at any planet in the indicated player's home system
13

Place one to four of your ships from any of your colonies onto the hyperspace gate
14
Offense invites first
The offense states which players they invite as allies
15
Defense invites second
The defense then states which players they invite as allies
16

17
Commit ally ships

Players cannot accept invitations from both offense and defense in the same encounter
19
Decline freely
Players may refuse any invitations received
20

21
Defense redraw rule
If the defense has no encounter cards, reveal remaining cards, discard them, and draw eight new cards, repeating until an encounter card is obtained

If the offense has no encounter cards, the turn ends immediately and all ships return to colonies
23
Reveal simultaneously
Both main players flip their selected encounter cards face up at the same time
24
Attack versus attack

28
