At the end of Nier Automata ending E,
when the player beats the bullet hell credit sequence, the game asks the player to sacrifice their save data to help others.
If the player chooses
not to, can the player later return to ending E, finish it, and then sacrifice their save data?
Does it depend on whether they
accept help in their 2nd playthrough of the credit sequence?
Yes, you are more than able to change your choice if you complete ending E again. This is what I did, as I did not have everything that I wanted to get done done when I completed ending E the first time. I deleted my save the second time I attained ending E.
I'm not 100% positive, but I am fairly certain that the bullethell sequence is nigh impossible without assistance, as after a certain point, you just start getting out-DPS'd with bullets and you can't shoot fast enough to hit any of the targets due to the sheer volume of destructible bullets coming your way.
