Release countdown (-5 days)

5 days-ish to the release of Arknights Endfield. I'm going to be in the first line playing it and I'm really curious about the story as I've tried to stay as spoiler-free as possible up to today. I know of the Factorio gameplay and the fact that they are trying to please multiple types of players, but that's pretty much it.
Hopefully it'll be a smooth launch without too many issues or instability. I know some may be inevitable, but I would like to avoid the disaster that Wuwa got in the first patch.
