The Crucible expansion was introduced to refine the existing game aspects. New nebulae graphics, an improved UI, time dilation and gameplay balancing were included in the expansion. CCP also added a line of third tier battlecruisers, which can fit battleship weapons, and the remaining Captain's Quarters for the Amarr, Gallente, and Caldari races. In addition to this, the engine trail effect was reintroduced.
