Part of "Map Labs #15: LVL 2." The third map in one of my favorite series when it comes to custom Half-Life 2 content. Custom weapons can be found while playing this map while displacing yourself into a theme consisting of medieval times.
You can get Map Labs: LVL 2 as a map pack here (I recommend playing previous Map Labs and Test Tubes as LVL2 consists entirely of sequels to older entries): https://www.moddb.com/mods/map-labs/d...
It's highly recommended to have Half-Life 2 and/or Half-Life 2: Episode Two installed when trying out this map pack.
