Sandbox Weapon Shop

Sept 16, 2025
- Splitted the money system for other mods
- Added the ability to remove ammo cap


*********************************************************************

A fun little script to make weapons worth getting by buying through hard earned blood money.

- You Kill, You earn Money
- Dynamic money value given depending on how much HP an NPC have
- Configuration Presets
- Option to split cash between players (Co-op Mode)
- Option to replace vanilla ammo with pickable cash
- Option to replace vanilla Wall chargers to become shops
- Option to disable pickups on vanilla weapons
- If you want to replace other entities with shop/money i suggest using the Total Replacer mod
- Option to buy anywhere (If enabled, you can say "!wblbuy in chat")
- and others!

- Spend your hard earned cash on Weapons, ammunition and entities!
- Add your own weapons/entities or workshop SWEPS in the shop
- Organize weapons/entities in shop by adding them in categories
- Two weapons with the same "SlotID" will make it so only one of the weapons can be bought
- Option to disable pickup for same slot ID weapons
- Add Weapon list Presets and create your own weapon shop list
- Quickly edit ammo and weapons in the list by right clicking to open context menu
- Quick add option uses an algorithm to do the setup for you (about 90% correct setup)
- Use "wblmoney_showsuggestedprice" to see suggested price of your currently held weapon

Make your own weapon list. If you don't want, I actually made a built-in preset for you to try:
Half-life 2 Tiered weapon list preset contains the following addons and must be subscribed to, so you can use it:
RTB:R Weapons Pack
Entropy: Zero 2 SWEPs
Entropy: Zero 2 Xen Grenade
ZBase EZ NPCs Content


After that, just go in game in gmod then open up the Spawnmenu -> Options -> WeTools -> Shop Options (Admin)
then select Half-life 2 Tiered under Weapon/Ammo List Preset.

Make the Weapon Shop entity under Spawnmenu -> entities -> Weshop

Get some profit by killing your enemies or friends!

Recommended to play with npc battle maps/scripts, here are some suggestion workshop mods to play with it:
Simple Horde Mode for Sandbox
gm_devbattle
Reinforcements System


I also made a guide in making it work in HL2 Campaign, check it out:
Play HL2 Campaign with Weapon Shops

Other useful mods:
Weapon: Setup, Transfer And Restore - Workshop If you get frustrated on losing your weapons (keep inventory)
Weapon Editor & Replacer for balancing/editing weapons
Alternate Model for Weapon Shop by Neeko
Customizable Entity Spawner after adding the shop entity on the list, should spawn around you
Modest Map Manipulator A mod that makes entities (like the weapon shop) to persist in maps







- If you are using Manual pickup (i.e. Vmanip manual pickup), this will conflict with my "Disable All Vanilla Weapon Pickup" and "Disable pickup for same slot ID weapons" feature. Simply uncheck them in my option and manual pickup will work
- I'm not gonna be invested too much in this mod, i simply want to share it. I mainly made this so that i can play with it myself so please don't expect too much support on my end :)
- Inspired by Counter-Life, a half-life 1 mod you should try it!
- This is also my first mod :3
- Dont look at my codes its messy >.<
