Tunnet

About this game

Have you ever wanted to be a lonely underpaid network technician who works 24/7 in an underground facility?

Design and Build a Network

Tunnet is a short game where you wake up as a robot technician in an underground complex.
You quickly meet your supervisor, who tasks you with building a computer network to connect the different bunkers of the facility.

Explore the Bunkers

You are equipped with a state-of-the-art drill that allows you to dig tunnels and find new bunkers to connect to the network.
The more endpoints you connect to the network, the more credits you receive.
But who knows what awaits you in this underground world?

Optimize and Debug

As you connect more endpoints, the network topology has to be carefully designed to route the packets efficiently and maintain a decent performance level.
Use the credits you have earned to unlock new devices to better manage and monitor the traffic.
Network incidents can occur at any time: get ready to debug and troubleshoot mysterious issues.

Features

• Build, optimize and debug a computer network in a first-person 3D environment.
  
• Dig tunnels to access the different bunkers and connect them to the network.
  
• Explore the facilities and unveil the secrets of the underground complex.
  
• Find a way to access the computers guarded by the creepy monsters that haunt the bunkers.

  Hotfix - v1.2.3

The note at the back of the handbook has been slightly changed to make it more readable on small screens. The system settings are now stored in the system_settings.toml file. This file is ignored by the cloud saves. The controller glyphs have been updated. Fixed a few typos in the dialogues and manual. Fixed a bug that prevented the boy scout questline to be completed when the DJ speaker was already replaced.
