Hi Nicklab, I haven´t seen aliens, but indeed lots of influences from major films are soon to be unveiled.
Perhaps the narrative of the series will get even more complex as the animation team explores the sources
from drafts and also EU.
I think for Kallus survival and similar situations (a guy holding from a column, a broken wall in a vacuum tempest)
there lack details, and maybe one of them could be the use of a repulsor lift device inside their belts.
SW never needed to explain technology, cause always the movies accepted it for granted, but
in times of realism in cinema, they could give a glimpse on that. Cheers
