This really isn't "news" news here, but it does seem interesting enough to inform you lovely readers of CS-Nation about. A Half-Life2.net forum member going by the name RomeoJGuy, recently discovered a new weapon hidden in Half-Life 2: Episode 1.
In [the] console type:

"hopwire_vortex 1"

then

"give weapon_hopwire"

Now throw it [via primary attack] and then press attack again to activate it. It is preferable to do it in an area with lots of physics objects. I also suggest you stand back lest you wish to be crushed into singularity.
So there you have it. Go play with your new toy if you'd like. You may also try "impulse 101" for more than one black hole weapon to use. If you're intersted in what this looks like, be sure and scope out a video demonstration.

how much fun does this look yo!
