Hi this is Kill Frenzy

I would like to know if I could use your weapons image from your website, and provide links to your homepage as well.

Well, I THINK Michal allows it.. btw you can get these pictures in an uncompressed format (Bitmaps) in your Soldat directory.
Soldat\Interface-gfx\Guns

Just make the green stuff transparent and there you go.
(I cant guarantee you that you're allowed to use it, but I haven't heard any complaints from Michal yet.)
