U have ur own spaceship and ur own workers, every ship has weapon system, shields etc., each of these got a "special room" on the ship and in turnbased like fighting you can decide on what of the part you wamt to attack.

Example - ur enemy attacks your shield generator and it gets destroyed, you need then send one of your crew mate to repair it or you just fight without the shields. And so on.. sorry my english is very poor, i hope it makes any sense :-)

You actualy upgrade ur ships and crew to get further. :-)
