: The storytelling in the Marathon games isn't perfect. For example: in
: Marathon: Infinity, by far the most sophisticated of the Marathon games in
: terms of level design and story, we're told by Tycho that "The
: Enforcers, as you may remember, are not vacuum enabled", but then we
: see enforcers hanging around on the vacuum level "Post Naval
: Trauma". What the hell? Are they holding their breath?
There are many other examples of this which lead people to question whether these were actually vacuum levels or levels with a non-human breathable atmosphere. See the Vacuum Levels section on the Story page.
It is quite possible that this wasn't mentioned in the original Volunteers series because it was already on the Story page. No point in re-hashing the already hashed. ;)
