If you aren't happy with the current power level of your shields and weapons, then be sure to install this mod. It will make your shields regenerate instantly and your weapons deal more damage, including turrets and missiles.
But not only the power level of the weapons has been increased. You will find out that your projectiles hit much farther than ever before, and your laser beams emit so much heat that no hull will be able to withstand them.
This is also a great way to finish battles much quicker, which again saves you time and money.
