|Mass Effect 2|
Unity restores squad member shields to full strength.
Shield emitters are optimized to produce a strong reliable kinetic barrier that can be active for hours. Because of the potential for interference, it is nearly impossible to run two active emitters simultaneously. When one kinetic barrier is down, it's possible to activate a second, but this will generally interfere with the reactivation of the primary barrier. With precise timing, a short-term kinetic barrier can be made that seamlessly retracts when the primary barrier regenerates.
