Hopwire Grenade
Adds the Hopwire Grenade, a cut weapon from Half-Life 2, as a usable tool in the 4th category. Prone to seemingly spontaneous detonation in freshly shook environments and very prone to chain explosions. Very destructive. Works best in medium-sized indoors environments.
Note: Uses the playermodel as well as the tool model to detect if you disturb a wire. May be at least slightly incompatible with older versions, mods that remove the playermodel, or tools with gigantic models. This also means a wire could attach to you, in which case, you’re likely too close to the device to survive.
