The recipe for what two crews yield which crew changes every 3 months. Note that Special crews can't be prestiged (those with the Shield emblem), and two Hero crews merged together will yield a Legendary crew member (not a Special crew rarity). The highest possible rarity is Legendary. You can merge two crews with same rarity to yield one higher rarity crew by putting the two lower rarity crews into the same bedroom and selecting Prestige option. There are many different crews you can obtain, each being from one of 7 rarity types (delineated by number of stars or an emblem): In addition, upgrading your ship (from level 1 to max level 12 using Minerals) increases space for placing more rooms.
Many room types can be upgraded multiple times (using Gas or Minerals) and crew members can also be leveled up (from 1 to max 40 using experience points). Your ship can contain multiple rooms that can hold multiple crew members. You command a starship from one of three factions (Federation, Pirate, or Qtarian) and battle other players or against NPC starships.
