The ONLY actual source port of Half-Life weapons in the whole Workshop. I wonder why no one made that before.
May conflict with other HL weapons addons, make sure to uninstall them.

  • Made using the source code - that means 99% accuracy
  • Correct GoldSource recoil
  • Original effects (explosions, muzzleflashes, etc)
  • Original view bobbing (+ WON style as bonus)
  • C_ models (can be disabled)
  • Fixed chrome textures using Lua and Paynamia's spheremap-to-cubemap conversions
  • Usable for NPCs
  • Predicted in multiplayer
  • Configurable damage values
  • Special options like unlimited ammo or loadout
  • Ability to unload weapon (used in Half-Life Co-op)
  • Done by me, which means quality

Includes all Half-Life weapons
  1. Crowbar
  2. 9mm Handgun (Glock)
  3. .357 Magnum
  4. MP5
  5. Shotgun
  6. Crossbow
  7. Rocket Launcher
  8. Tau Cannon (Gauss)
  9. Gluon Gun (Egon)
  10. Hivehand
  11. Hand Grenade
  12. Satchel
  13. Tripmine
  14. Snarks

can someone make a mod the makes the half life source npcs and the half life snpcs drop these weapons?

Is there a way to get the models without getting a different mod? I want to play Half life Co-Op but I don't think any other mod is supported by it in terms of weaponry. And, yes, I have all the Half Life: Source content but they are still appearing as errors.

Are you ever going to add the hidden Glock silencer functionality? I know the feature might be useless but it'd be fun to mess around with it.

I managed to dnwload the HL:S game's content via a website, and downloaded this addon. I am enjoying killing Combines with the 9mm grenades of the MP5 in NPC Arena ;3
Very complete and good addon!
