Someone Selling Killing Floor?

i just view some gameplays and stuff and i want that game, im buying it for
4 keys due to halloween sold out.

 

I'd say just be patient. It goes on sale frequently, and when it does, it's usually about $5.

 

i have no patience lol, but you are right
anyway im giving 4 keys for it if someone is interested

 

I'd say you have about a month at most to wait, as they do a Christmas update every year that starts about halfway through December.
