I'm looking for a font similar to Fight-this with Polish characters (Latin).
If you don't know the history of this font, it's tied to the 1999 movie "Fight Club":
So, it's reasonable to say that there's probably no version of this with Polish characters around. Here are a few options:
Another option would be something like DIN Condensed Italic:
Basically, any sturdy sans-serif where you can get a "Condensed Bold Italic" variant. Experiment and see what works. The stuff like the modified "B", "G", "R", and "D" you can probably do pretty easily in Illustrator.
