Unfortunately this mod is just like all the other inventory mods out there that had potential, but fail to do the basics at least for what I am personally looking for in an inventory system.

- I'm sure someone can use this mod but for campaign/single player this add-on is basically useless. Not only do you have to add the various items you want to put into your backpack via a config in a separate folder inside the actual files of the mod because there is no menu in game to do it from, but the author doesn't even add the basic entities from HL2 for you.

- If you haven't noticed because this is for DarkRP it definitely does not work with ARCCW/ARC9/TFA base weapons because the mod isn't reading those weapons so it has no use for Combine/NPC Weapon Replacements that you can pick up off the ground when you kill them.

- No sounds for opening/closing the inventory, and no sounds for picking up items.

Besides the glaring flaws for Single player, I am sure for DarkRP this is useful! I wish no hate upon the author I am sure you put a lot of effort into this mod, however my disappointment was pretty big when I see a new Inventory mod only for it to be the exact same like the other inventory mods on this workshop.

If you are like me and play Single player Campaign mods/maps or even just the base HL2 Campaign and are looking for an inventory system, your best bet is this mod currently.

What this mod does:
- Relatively good design its some kind of League of Legends design however there are variants of this mod that you can find on the workshop, also has a money system though it is purely cosmetic.
- Pick up any entity whether it be Weapons/Armor/Health/Ammo (It also detects bases like ARCCW/ARC9/TFA)
- Opening/Closing/Pickup sounds it even plays a sound when your inventory is full. Why is this important? Because it means if you extract the mod and mess with the files you can add whatever sounds you want to replace the sounds already being used!

What this mod does not do:
- Does not save your inventory on level transitions
- You can't innately pickup props from what I am aware of, however just like this mod you can just add whatever props you want to the config.
