Alien colonists

[Epic]

If you think about it you had a spaceship and your goal is to set up an automated factory and do whatever you want. Well the planet appears to have no intelligent life yet you can live on the planet, so why didn't anything live on the planet before you arrived on it.

My idea is that you add a new enemy that has weapons and gear... And it's very own factory setup. A small one with only a bit of metal nodes nearby that it harvests an collects. The aliens would NOT have too low level stuff like pistols. They would have pretty good weapons and would stick within a certain radius of their outpost(structure at the center on their base). It would be possible for you to raid their outpost and use their setup as your own... After they are defeated.

Even after your world is generated, the planet you are on could be invaded by an alien race trying to colonize the planet. Sometimes the colonist aliens would also be peaceful and may sell you resources in exchange for a currency or another item. This way the game is more dynamic and can change mid game. (But aliens cannot colonize areas that you have a structure within a certain radius of).
