Tunnel 10

Tunnels, underpasses and underground structures. Tunnel 10 is one of the more popular entries in our tunnel catalogue — the code listed above was pulled from the same dataset on the last sync, so it should match what is currently working in-game. Tunnel entries are typically large plug-ins. Pair with road / highway entries to build connected routes.

What is this cheat?

Out of the Tunnel section, Tunnel 10 is consistently one of the more frequently copied entries — players keep coming back to it for both singleplayer and sandbox builds.

How does it work?

The Tunnel 10 code is not stored on our servers — it lives in the source game itself, which is why typing it into a new session unlocks the Tunnel asset instantly.

How to use it

• Open the source game and head to the in-game code field — usually under Settings, in the phone menu, or in a dedicated Cheats section.
• Type the code exactly as shown, including any capitals, hyphens, or punctuation.
• Submit the entry. The Tunnel asset will be added to your session immediately — there is no wait or queue.
• If nothing happens, restart the source game and try again — some versions only recognise Tunnel codes after a fresh session.

Frequently Asked Questions

Where do I type the Tunnel 10 code?

Open the source game and find the cheat-code input field — usually inside the in-game phone or settings menu. The tunnel section's code field accepts the Tunnel 10 value directly.

The Tunnel 10 code does not work — what now?

Make sure you typed Tunnel 10 exactly as shown, with no extra spaces. Some games only accept tunnel codes after a fresh session — restart the game and try again if the entry is rejected.

Is the Tunnel 10 code case-sensitive?

Most in-game cheat codes — including Tunnel 10 — are case-insensitive. If the typed value is rejected, try it again in lowercase to rule out a capitalisation issue.
