With this expansion, Nexum Galaxy becomes a complete 4X game (eXplore, eXpand, eXploit and eXterminate). It also introduces asymmetry in the factions, technology, new resources, more ships, and a special multibattle mode.

It also increases replayability by adding new Systems to those included in the base game, as well as Event and AI cards. Play several games simultaneously, by sides transferring ships and resources between tables, through Wormholes. Navigate and fight for the different Sectors, orienting yourself with the map and atlas of the Galaxy.
