Choose from 10 different Strategic actions that can be used once per turn, each having 4 supplemental effects that are unlocked throughout the game
Take part in the living economy of an empire, where commodities rise and fall with value based on the decisions of the players
Manage diplomatic and trade relations with planets in your empire by choosing whether to barter with them or conquer them
Gain trade advantages by conquering enemies of planets you have open trades with, while risking sanctions for attacking those planet's allies
Choose carefully which technology advances you specialize in, and research special synergized technologies that combine the effects of 2 different technology trees
Take part in tactical formation combat, where ships are ordered to protect those behind them, allowing your firepower time to take out the enemies ships
Over 40 tactical actions can be played throughout the game, and are distributed at the beginning of each round. These actions are distributed randomly to each player, so other players can't see what you have planned
Vote on more than 30 political agendas that can fundamentally alter the rules of the game, exhaust key planets, place ships on hold, or target a specific player to their benefit or demise
