Since some moron scammer came on here trying to sell a custom version where you could apparently change the Username, he never sent me the Binary to prove it so I stopped him selling it.
I since bought the latest version and stripped it all down and re-modified it all, it will now support Anticheats and Customer Username/Password.
It has many features such as;
Steam ID Spoofer
And much more
I am selling this on a lifetime license with server authentication for 5 users per purchase so you can buy for your team. Your server must support Linux, but I also have an amxx version if needed.
Price: 30E Lifetime
I am in the process of modifying the CS:S Version as well
Credits to Iniuria, if they was still selling this I would not of bothered editing it.
