Ok, it's stupid playing in daytime, the sun is shining on my monitor, and im not seeing to much on whats happening. And when you stupidly cant use you light when walking in the stasions, I see almost nothin. So at the end of the stasion, Khan want's me to buy mask and filters. But the two store owners I can see, dont sell it. So are the mask store somwhere else, or Im I not seeing what I should be seeing at the right place?
You can't, there's just a box with a few filters. I do wish you could buy filters in Last Light instead of everything you need being along your path on the surface.
Ye in 2033 you could buy filters. I miss this but if you look hard enough there are lots of them hidden on your journeys. Also you could try "shallow breathing" (my name for it). This is where you remove your mask outside until you think you are about to die and then put it back on so you don't, keep repeating this and you will end up saving lots of filters, came in handy when I played through ranger hardcore.
Spoiler When I caught up with Pavel the last time I had close to a hour of filters... And I'm sure I missed quite a few of them as these were mostly the ones that were on dead enemies or elsewhere in the path
