Tunnel 1

Tunnels, underpasses and underground structures. Tunnel 1 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?

Players using Tunnel 1 usually do so as part of a wider Tunnel setup — spawn the asset, then trigger any companion effects from the in-game menu.

How does it work?

The source game periodically refreshes its cheat table when you load a new session. Entering Tunnel 1 after a fresh load is the most reliable way to confirm it is still active.

How to use it

• Load the source game, then open the in-game menu and find the cheat field. The exact location depends on which source-game version you are running.
• Enter the code in full — the source game looks for an exact match, so even a typo will result in failure.
• Apply the entry. Within a second or two, the Tunnel asset should appear in your in-game menu or spawn list.
• If the entry fails, quit to the main menu and reload the session. This refreshes the Tunnel cheat table and is the most common fix.

Frequently Asked Questions

Where do I type the Tunnel 1 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 1 value directly.

The Tunnel 1 code does not work — what now?

Make sure you typed Tunnel 1 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 1 code case-sensitive?

Most in-game cheat codes — including Tunnel 1 — are case-insensitive. If the typed value is rejected, try it again in lowercase to rule out a capitalisation issue.
