Game : CS 1.6
Server : 89.149.242.27:27500
the server is a surf map server, where you get instantly respawned if you hit the ground/die.
I've noticed some people using a bug where they can become invisible and teleport to anyone they want and knife them to death.
I was wondering if anyone here could explain how they are doing this so I can possibly come up with something to make this bug apply to all servers.
