right now we have lots of dark runners, raptors, replicators, etc that you shoot and forget. How about asteroids that you shoot and collect to build a planet. They could come in 4 types; common-abundant, uncommon-rich, rare-mega rich, and elite-5Xmegarich that require 3 attackers and break into 3 pcs when killed. You would need to have a mission running with these to give you an artifact (eg a molecular bonder) to assemble your asteroids into a planet. Planets will be built according to structural size and richness. eg; you would need 51-uncommon asteroids to build a large-rich planet
