Often after I've mined an asteroid dry I find the security status becomes "low morale". How do I fix this?

I only ever build one resiblock on my asteroids as I've never found any need for more than 250 population. I always build a medical centre, pleasure dome and security centre. The surplus population is around 200 as well. Will hiring a colony supervisor fix this? Because I don't really want to do that as it just seems unnecessary and a waste of money.

Any tips?

Since it refers to security it could be that they feel vulnerable, in a Total War game if you don't have any units garrisoned in your city your citizens get scared. Try a couple of small warships or so and see how they feel knowing there are guns defending them.

Just a rough guess, not played for a few years. By a few I mean almost 15 :D

Good idea, I hadn't thought of that, thanks. I'll give it a shot next time I fire up the game (which could be some time away since GTA V has landed for PC :D).

I played this game when it was new, so my mind can play tricks, but I remember that security centre supports150-200 people max.

Keep security tight, build a pleasure dome and most important of all: KEEP THEM BUSY! If you have a bunch of surplus population (that means non-working pop) they get bored and social unrest will rise. If you have too much surplus population, tear down some resiblocks.

So... here I am 4 years too late, but maybe someone will benefit.

You don't need pleasure domes. Just make sure your asteroid is secure using security centers. One for 100 people. So 1800 people? 18 security centers.

1800 people means 1800 bucks per tick. Get those credits in!
