Hi everyone! 

We’re happy to announce that the Beta Testing for Full Release is now open to all players who own Underground Garage!

We kindly ask you to not stream or publish Underground Garage Beta content on social media!

How to Join the Beta Test?

It's super simple:

• Join our Discord server

• Look for the #join-ug-tests channel

• React to the first message to get the tester role

Here’s what’s new: 

• Vehicle roster expanded from 10 to 20 cars

• Engine selection increased from 8 to 15 options

• Vehicle classes include compacts, sedans, sports cars, and muscle cars

New Features:

• Fluid Maintenance System: Engine oil, coolant, and brake fluid mechanics

• Fuel Octane System: Three fuel grades (95, 98, 100) affect engine performance. Higher octane enables more power on modified engines, while incorrect fuel causes engine knock and damage. Wrong fuel or empty tank prevents driving. Auto-fueling selects the best fuel for each engine.

• Battery Service Station - New workshop equipment for testing and regenerating batteries with voltage, capacity, and cell diagnostics. Batteries have two states: charged and uncharged.

• Expanded Part Dependencies - High-performance engines now require upgraded drivetrain, braking, and suspension components for a comprehensive vehicle building approach.

• Campaign Completion - Main story concludes with final missions.

• Enhanced Procedural Missions - Expanded task variety beyond basic repair jobs with logical integration to core mechanics.

• Racing System Improvements - Adaptive AI difficulty scaling, reputation-based event access and betting limits, streamlined race UI displaying requirements, rewards, and opponent data.

• Race Mode Selection - All race events accessible in three modes: Practice (new), Time Attack, and Race.

• 1v1 Betting Races - Wage money against AI opponents to fund your parts. Players can bet their own car to win their opponent's vehicle.
