【Arknights】OF-EX6 Hard mode (Ch'en S2 Battoujutsu show)

Technically I can use the same strategy as normal mode that I uploaded before, but the strategy required a lot of micromanagement and I read from somewhere that the specter actually has increased armor (not sure about hp) but is not written in the description. Fed up, I researched and tried other strategy and finally landed with this one which has less micromanagement (just need to time Chen S2) . good thing about this strategy is every member is replaceable with equivalent operator.
hope this video helps!
