I just checked the vfs0 files in the newly released Metro 2033 Redux (I think Last Light Redux uses the same files, since the engine was upgraded for both), but it looks like unpackerLL.exe (program for unpacking Last Light's .vfs0 files, http://goo.gl/8BMLuD) can't unpack them (something about too many indexes).
Here's a sample of Metro 2033 Redux .vfs0 file (also .vfx file, if I remember correctly, it was needed too):

I own the games, so if you need any other files, please feel free to ask.
Thanks in advance, I would really like to port my Hungarian translation from the original Metro 2033 from Redux
