Upgrading your fortress is where the magic happens - you can add new defenses, like laser cannons or missile launchers, or boost your base's health and energy output. The upgrade system is deep, with tons of options to customize your base to your playstyle. Whether you're a fan of brute force or sneaky strategy, there's a way to build your fortress that fits your approach.
Standout mechanics like the ability to research new tech and construct specialized buildings make the game feel incredibly dynamic. You'll need to balance your resources carefully, as upgrading one thing might leave another vulnerable - it's a delicate dance, but super rewarding when you get it right. And let's not forget the epic battles against massive boss ships - your fortress will be put to the test!
