Halflife2 Blue Gravitygun

Completed this game last night and really loved the new gravity gun.  I won't say much about it as I don't want to spoil the game for anyone but if you've finsihed and want to make this appear earlier in the game here's how:

Enable the console:
Options > Keyboard > Advanced > Enable Developer console

Press the tilde key (usually under escape key) and enter the following:
sv_cheats 1
map d3_citadel_04
*wait for it to load*
changelevel d1_trainstation_01
*wait for load*
give weapon_physcannon

You might want to change the d1_trainstation_01 map to something you want.  Use the "maps" command for a list.
