<Half-Life 2> weapon_hopwire is a point entity available in the Half-Life 2 series.

Entity description

Note:Much of this article lacks verification and needs to be properly confirmed.

A recently discovered "black hole" grenade whose explosion will create a black hole vortex strong enough to even destroy striders. Is first thrown and then activated by a second attack press, like a remote mine.

While not in any currently released Valve product, this weapon can be enabled (so far seen in ep1 and smod) by entering the following into the console:

hopwire_vortex 1

give weapon_hopwire or give npc_grenade_hopwire

This will provide you with only one hopwire. An additional 5 hopwires can possibly be obtained through typing impulse 101 into the console Not sure if impulse 101 works with it, Doesn't in portal..

You can also have them in Source SDK-Hammer by going into a entity, Then changing the name to weapon_hopwire and hitting enter then apply. It will come up as "Obsolete" with the special image but it DOES turn up in-game.

Warning: Crashes has been reported after enabling this weapon. Use with caution.


The name "Hopwire" was taken from a grenade originally intended to be in Half-Life 2, which would, when thrown 'hop' into the air, and shoot out tripwires to nearby surfaces. If the tripwires were broken, the grenade would detonate. The old Hopwire can be used in the mod "Missing Information".
