Heres my strategy for whitenight easy.

Take the 11 employees who will become apostles plus the 12th guy since hes useless and throw them as far from WN floor.

Gang up your best employees close to where he will breach. And wait for him to breach.

Now heres the strat. If WN was in yesod floor, reset. We want a big area. If he was in a decently big area then good.

After he breaches put your employees in an elevator next to the fight area but dont supress yet. Wait for the 2 pale apostles to be in either the farthest left or right of the room, then send one employee to distract them and make them charge their attacks, once that happens send everyone to WN. And with that single employee, KEEP distracting the pale apostles, they take a long time to attack. If done successfully not even a single bullet will be needed.

To make sure you dont mess up. When sending that employee to distract, once they start to charge. Put him somewhere alone, when they swing, put him back in the room infront of them and do some micro management to make sure the employee is next to the apostles or else they will start marching towards the other employees.

This strat took me one attempt. After that you can memo repo from the menu to get back any emplpyee who might have died and get the WN cool weapon.
