SPRT Space Pirates
They are a hostile faction of pirates that harass the Engineer relentlessly. Their aim and purpose is unknown, but what is known is that they desire the destruction of anything the Engineer produces. Most of their vessels seem to be en-route to a destination set past the boundaries of the map. Occasionally, there will be a location of a pirate base, which defends itself with drones from a distance. Drones seem to be their favorite method of attack against the Space Engineer. Finally, SPRT's color scheme seems to vary between bright red, obsidian black, dark grey, and light grey. They are the first true faction (depending on how you look at it) introduced to the game.
