This Ask Cryptic contains answers on power management, exploration and small ship tactics. A big thanks goes out the development team for taking the time to provide these answers!
We’re not using anything like a traditional MMO “mana bar” for energy. Your ship’s Warp Core provides power, and you allocate this power to individual systems – shields, weapons, propulsion, etc. But you won’t “run out” of energy and have to wait to fire phasers. That’s not fun. The more power you allocate to weapons, the more effective your phasers become.
