I have come back to Metro 2033 for a ranger easy play-through and have reached Polis with zero filters for my gas mask, and to my surprise they are not available at polis. Obviously I could go back to the last place where they are sold, but that is prohibitively far.

Does anyone have any game-play ideas for continuing with zero filters? Otherwise does anyone know any good ways to mod the gamesave to produce more filters? I have the tool "360revolution" that offers the ability to mod saves to "god mode" and "infinite ammo", but even if these work it sounds to me like cracking a nut with a sledgehammer.

  • A bit specific so I'm not holding my breath (...sorry). Isn't the move away from cheats and customizability with these consoles tiresome? Mar 19, 2013 at 1:09

    do you have absolutely 0 or close to it? There's a way to 'cheat' the system by putting on and removing the filter quickly without using it up.

    I can go back a level and have a few filters, go the main way through black station and try that. I understand Artyom lasts 30sec without one, I'll have to see how far I can get (It has to be far enough to fall through the elevator?). In that case, I hope there are filters at Sparta Base.

    I went back to the surface section before black station, and using the tactics you mentioned manages to save 11 filters. Thanks. Mar 19, 2013 at 22:31

As soon as you leave the station, turn left (don't go into the ditch), there's a dead body there from which you can collect some filters.

I found this info in this thread

  • I was SEVERELY annoyed with having to go outside with 1 filter at ~:01. When dude said I had to go outside to the library, I just threw my hands up and started looking for a cheat. it took about :15 to find this tidbit. Thanks.
