It’s another OblivAeon One Shot, but only regular difficulty and with probably the easiest shield (do objectives, which is going to help you anyway). Obviously, your results may vary. I managed a Mint, the toughest part being reminding myself it was a One Shot so don’t use undo.
It’s true what Luminary said in the blurb, sacrifices had to be made. In my case, the entire starting lineup, 5 other heroes, and 2 environments.
