[Corpus Railjack] The production line side-objective is godawful.

[Chroia]

Unlike Volatile, where you're navigating between changing points while traversing a contained, multi-level tile,
the production line jerks you back and forth along a single, unchanging linear path between the front and back of a 7(? forgot to count last time)-tile long milk run to kill a couple of nuisances.
And then repeats it another 3 times.

It is, in a word, dull.
Unlike Volatile, there are no factors changing the route (different vents, enemies push you around the various levels, Engineers), and the route boils down to a single through-line from door to door.

Not that the central tiles are small by any means, they're simply entirely irrelevant to anything.
The only impact they have is if you decide to go sightseeing rather than play your mission.
(For that, though, they're pretty cool.)
