The scientists at Black Mesa have been hard at work adding a freeze ray to the secondary fire on the Egon gun. The freeze ray will "freeze" a player in their tracks and prevent them from moving (it will even freeze them in mid-air). The freeze ray will only fire in short bursts (2/10ths of a second) and takes 5 seconds to recharge after firing. The player who is frozen will not be able to move for 3 seconds and they will see a blue screen fading back to normal during this time. The other players in the game will see a blue glowing shell around the player to indicate that the player is frozen.
If you wanted to be really fair to the frozen player, you could make further modifications so that the only weapon that would do damage to the frozen player would be the crowbar. That way the frozen player would have half a chance to get away after being frozen. As it is right now, it's WAY TOO EASY to freeze the player then hold the primary fire on the Egon gun until the frozen player is dead.
The original code in the files will be shown in CYAN.
The new code in the files will be shown in RED.

Now save the modified player.cpp file, rebuild the mp.dll file and you
should be able to use the secondary fire on the Egon gun to freeze
players!
