Basically a simple plugin that shows a menu when you defuse the bomb that gives you the option to cut one of 5 wires to disarm it immediately (the other 4 cause it to explode immediately). Basically a Sourcemod recode of this Eventscript plugin-

You should still be able to defuse the bomb the normal way, this would only be of any use if normally there'd be no chance of defusing it.
I would use the ES script but we're trying to keep the extra plugins down to a minimum and with Sourcemod already on it this would be far easier.
