Plan your next Tunnet session

Our independent guide helps you think critically about Tunnet’s core systems without promising hidden bonuses. By observing how each mechanic interacts, you can refine your approach, balance network performance, and enjoy the underground mystery at your own pace.

01 / THE GUIDE

Map Your First Topology

Draw a simple diagram after connecting the first two bunkers. Note packet routes and compare latency estimates before adding more nodes.

  • Observe how adding an endpoint changes traffic flow before spending credits on new devices.
  • Compare the performance of simple versus more complex topologies to see which maintains steadier packet routing.

02 / THE GUIDE

Compare Drill Paths

Create two tunnel routes to the same bunker using different angles. Record the time taken for each and assess which path feels more efficient.

  • Map the tunnel layout as you dig to avoid retracing steps.
  • Use the drill to test different routes and compare how quickly you can reach new bunkers.

03 / THE GUIDE

Credit Allocation Test

Spend a small batch of credits on a monitoring device, then on a different device. Observe which investment yields better stability during a simulated incident.

  • When an incident occurs, pause and review recent changes to the network.
  • Compare incident frequency before and after unlocking new management devices.

04 / THE GUIDE

Incident Response Log

When a network issue occurs, write down the steps you took to resolve it. Later, compare logs to see which actions consistently restore performance fastest.

  • Take note of monster locations to plan safer tunnel routes.
  • Compare the layout of discovered computers with your network map to spot missed connections.

05 / THE GUIDE

Leaderboard Benchmarking

Record your final network efficiency score and compare it with the top five leaderboard entries. Identify any pattern in their network designs that could inform your own.

  • Check the Leaderboards to gauge how your network efficiency compares to other players.
  • Enable Steam Cloud to ensure your network designs are saved between sessions.
