HOW TO USE THE EMERGENCY POWER CONVERTER
Holding X (Xbox One) / Square (PS4) / C / JOY 7 and using the left thumbstick/mouse wheel / POV to navigate the pop-up menu, you can instantly shunt all power from one system to the other, giving you the advantage of overcharged engines or overcharged primary weapons at a moment’s notice, at the expense of the other system.
This will not change your power distribution settings, so if that system is not currently overcharged, the additional power will start to drain. Bear in mind that – depending on the power levels before using this ability – converting power to engines may leave you without primary weapons for several seconds, and converting to primary weapons will severely impact your speed for a short time. That said, this ability can provide a quick tactical advantage to make a quick getaway or to deal heavy damage in a pinch.
