Tunnel Brawl Friend Pass Demo

One purchase. Two players.

Tunnel Brawl Friend Pass lets you join a friend who owns the full game. Download the free Friend Pass, sign in with your own Steam account, accept your friend's invitation and meet in the lobby. Both players ready up; the owner starts the match. You play against each other in a complete 1v1 underground tank battle.

Dig your own routes, manage your tank's energy, flank your opponent and fight for the enemy base. The guest uses the same combat rules and tank strength as the owner. After the match, return to your lobby and play again. Solo local training lets you practise driving, digging and shooting.

How to play

• One player owns and launches Tunnel Brawl.
• The other player installs Tunnel Brawl Friend Pass on their own Steam account.
• The owner chooses “Invite a friend for free” and sends an invitation.
• The guest opens the link or pastes its code into “Join a friend”.
• Both players ready up in the lobby; the owner starts the match.

Access rules

The full-game owner must be in the same lobby and match. One Friend Pass guest per owner at a time; the owner may invite a different friend in a later session. Friend Pass does not provide an independent full-game licence, online play without an owner, ranked play, or the ability to sponsor another guest. Online play requires an internet connection and Steam. Your profile and eligible progress remain with your Steam account if you later buy the full game.
