Hello, I wanted to ask how can I change the names of the bots? I know its possible, because I downloaded the non-steam version of Black Ops, which is running on some random server from NemexisOps-SteamPro. And they changed from [3arc] to [IW4].

I know it's possible somehow with cheat engine, but I got no idea how do to it. Can someone please tell me? Thanks in advance
