[Arknights] My Clear of TN-4 Ultimate Trial (TfN 4)

This was my first successful attempt. I tried similar strategy to what I did for the Spectacular Trial with slight variations until it worked.
I used the Darknights Squad because I found their utility more useful for the clear than the Blacksteel and the “ammo” squads. Plus their squad buff was pretty universally useful for my operators (tho I didn’t use it that much with my own operators besides Texalter).
I chose not to use the device during the 2nd wave because I wanted to simulate a fresh attempt and see if I could consistently beat the wave without the buff.
