❓ Underground MLO FAQ:

Q: How do players find the hidden spots?
A: The entrances blend into the map (like rusty grates or abandoned doors). This encourages natural discovery and exploration, making it more rewarding for players.
Q: Can I tweak the rooms for my server’s theme?
A: Yes! All props are editable in CodeWalker. You can add your own gang tags, extra crates, or booby traps to make the space uniquely yours.

Alen Carter –
Best Tunnel for Gang RP
Jacob Mendez –
Love the atmosphere! The hidden rooms and passages make it great for roleplay. The only small issue is the lighting could be a bit brighter in some sections, but overall a solid and immersive MLO.
Ethan Ross –
Excellent design! Works great with my QBCore server and players love using it for underground deals. The attention to detail is top-notch. Definitely worth the price.
Lucas Gray –
Cool hideout for any gang RP. Easy to install and no texture bugs at all. A few more props would make it even better, but still one of the best underground maps I’ve tried.
