I made a movie of me playing it in a way that works really well, which can be seen here, if anyone needs a guide:
Part 1Part 2Part 3 To my mind it cannot be a problem for anyone if he plays it like that but of course you also have to want to play stuff like that. I could imagine that people just are annoyed by such things...
Anyway respawn with ingame option is pretty crazy in terms of xp gain imo. I personally would ahve preffered a more lore like ingame solution where it stops in the town once you kill the engineer for example...
And maybe in the academy it should take a little longer for the enemies to spawn because it takes all the fun out of exploring - which is doubled complex there with the helmet - with enemies that kill you all the time.
