The Qtarian Faction is one of the 3 starter factions you get to pick in Pixel Starships. The other two being the Pirate and the Federation. Qtarian Ships have the most amount of grids, but many of them are wasted due to bad design.
The main difference that separates Qtarian ships from the other factions is their vertical ship designs. These incredibly tall ships will always need many Lifts because many rooms will be inaccessible without it.
The main color scheme for the Qtarian ships is a dark yellow. They seem to have many Shells along with being vertically long. Qtarian ships also has a separate hull branch which can be switched to at level 10 called the Hybrid.
