HL2 Episode 1 Black hole grenade

This is a rather interesting find by a guy by the name Romeojguy, he has found by entering two lines of code into the HL2 Episode 1 console he had gained the "black hole grenade", I have personaly tried and tested this and i can confirm it does work although don't activate with god mode on or your game will crash. anyway's enough of me going on here's the line that need to be entered separately

hopwire_vortex 1

and then

give weapon_hopwire

 

hint of advice don't be near it when it goes off.
