In Terracore you have to be a strategic citizen and survivor as well because when the world is destroyed and the disaster came on the is nothing left in the planet except Scrap so you have to find it and you have to collect as much as you can so you would be able to survive in the chaos.
Other players would try to steal from you so you have to focus as much as you could and you have to deal with this danger with your weapons which you could buy with Scrap that I have mentioned to you.
So as a good citizen you have to buy Scrap and collect it to have items and resources so you could build your new planet and as a good survivor you have to collect and have much weapons so you could defend yourself.
So as you can see it is a strategic war game and you have to focus well so you could keep your resources and you could keep yourself safe in this game there is no limits and what you have to do should do quickly or you can not survive in the great game.
