Then build a Dilithium refinery to get resources, and continue to build up your base with Shipyards, Research Facilities, and Turrets for defense. A good idea with base construction is to always build a turret or two near a building for defense. There are also various types of obstacles in space that can make the game a little more interesting. Wormholes can warp you from one side of the map to another, Black Holes can instantly swallow up any damaged ship, Asteroid belts prevent movement, and Planets increase crew replenishment if a Starbase is built near it. These are Metrion Nebulae that show down and damage ships.
All radioactive nebulae are yellow and they kill off a ship's crew at a steady rate.
Metaphasic Nebulae that speed shield recharge rates and remove negative effects from ships. These slow ships while having the same effect as Blue Nebulae. Also like StarCraft, the game is split up among the four races. Once you complete those four story lines, the Omega campaign will be unlocked.
