Seems to be precisely like an aigis star rush event, and yeah 8 or more stages.

Doubt it will be very difficult. I mean, do consider that it is the first event we get and that it must take into account that we started playing 4 days ago (unless we inserted the Canadian cheat code). We also have a whole 2 weeks to do it so i'd assume that if you cannot clear this you'll never clear anything ever and remain a nameless character that walks from point A to B in a 2 second movie clip
