A korean Counter-Strike? I haven't found any screenshots other than those on the index page. To register you need a KSSN (Korean Social Security Number). There was a guide somewhere on another forum but the poster deleted it because "They didn't give him feedback". So if anyone could write a registration guide I'd be thankfull :)

Thanks to Necreon for the Net Marble registration guide.

Warthog! I'm now downloading the client. I'll post some screenshots in about an hour or so.

you'll take the risk if you continue doing that
