Atlas, the 2D RPG Roguelike survival sandbox with complex fighting strategy in endless randomly generated universe. Implementing real science and projected real world development in game..
Here is some preview of how we imagine ship equipment will look like. In each ship is a room or place where you can put weapon, engine, fuel tank, cargo bay etc...
There will be no limitation how you can equip your ship except some logical ones like you need to have engine to move ship, you need to have fuel tank in order to fuel the engine, you need to have cockpit to steer your ship and you need to have a life support system in order to not suffocate your crew to death.
Well, actually you don't need to have all that but then your ship will be floating chunk of metal in space and playground for looters, pirates or other space infestation out there.
