open up UT2004 find a non-secure server and join it
while in game, open up your console and type this

change character .

you just crashed the server. make sure you go to the character menu and change it back to the character you had before or else you will crash UT2004.

doesn't work, says Unrecognized command or something..

i said unsecure servers, aka unprotected no anti cheats no patches etc.

Isn't it changecharacter . instead of change character .

I use changecharacter .
It's even binded to a key.
[key]=changecharacter .

That looks like a copy / paste off of one of my old youtube video desciptions lofl.

But yeah its changecharacter . And in general it only works with demo servers, I've yet to see it work on a full version server.

Used to work, till some fucktards started leaking it. But still, there's a few ways to crash servers and such

Yeah now everyone in demo knows this command. It's ashamed thought. I also need to speak with you HyPeR-X about another one, can't get on IRC or the other forums because I'm at school and my host is blocked or some shit.
