The Modular Gauge system allows players to configure each gauge component individually.

Ring, background, needle, redline, tick marks, labels, and logo placement can be adjusted independently. Rather than relying on fixed presets, players construct their own layout from discrete parts.

Gauge components may be freely available, purchased, or unlocked through progression. Visual customization is treated as part of the build process, not separate from it.

The result is a customizable instrument cluster that feels integrated into the vehicle itself, not layered on top of it.

Performance remains the priority. Customization enhances presentation without compromising readability.

2ADVANCED Music

Underground will feature original music and gameplay audio created in collaboration with 2ADVANCED.

This includes custom race finish sound cues and in-game audio elements designed specifically for the Underground environment.

Select 2A tracks will also be available through the in-game MP3 player.

Check out the music on YouTube and Spotify.

State of U.G.R.E and it's feature so far (Updated Feb 13 2026 1:19 AM, Updates Log Report)

Engine Sim

• Reworked torque curves logic (Now it actually working)
• Improved torque scaling
• Reworked split torque curves NA and Boosted (Calculated based on current boost pressure)
• Engine load (Updated but still working weird)

Induction Sim

(Previously known as Turbo Sim) (No update on it this time)

• Completely Reworked forced induction logic
• Turbo gating + custom upgrades/induction type: single turbo, twin turbo, supercharger
• Improved boost behavior (Working but WIP)
• Anti-Lag system (With Toggle on/off)
• Improved power gain from turbo (Now it actually using engine split curves function properly)

Flywheel Sim

• Flywheel mass directly affected RPM responsive
• Added clutch/throttle state awareness

Transmission Sim

• Reworked with max speed per-gear logic (didn't work on GTA automatic gearbox)
• Custom gear ratios + final drive (still didn't work on GTA automatic gearbox)
• Custom clutch management (still a bit weird but clutch no longer disengaged when you brake)
• Gear tunning (do nothing as it didn't apply to GTA automatic gear box)
• Manual gearbox mode (Planed not in current build)

Tyre Sim

- Reworked

• Added per-wheels/axle based slip/stress calculations
• Simplified Pacejka tyre-model

Differentials Sim

(For AWD and FWD only)

• Reworked with new per-wheels logic
• LSD (Highly experimental that's seems like it didn't do anything)
• Active AWD diff system (basically a haldex)
  • Cut engine torque based on tyre slip/stress to help reduce understeer and send drive bias rearward to further enhanced the effect
  • On launch it move drive bias to 50:50 which didn't really help much but it's working (Currently not working)
• FWD understeer/wheelspin reduction (Now it's working with very aggressive torque cut)
  • With data from tyre sim it able to detect wheelspin and then cut the engine torque to reduce it
  • Also cut engine torque based on slip/stress to help reduce the understeer

Brake Sim

• Reworked with per-wheels pressure and fade behavior
• Functional brake temperatures
• Improved brake proportioning
• Brakes faded from overheating (Finally working and improved)

Particle FX

• Reworked FX sync function (WIP)
• PTFX offset edit/save switched from JSON to server-sided KVPs
• Custom Anti-Lag particle FX (Now with fully functional RBG colouring)
• Light trails
• Brakes glows and smoke
• Particle FX sync (Reworked need to be test in multiplayers)

Overview

This update introduces several new core systems focused on accessibility, immersion, and player identity, while also laying the groundwork for future functionality. Alongside major backend upgrades, these changes aim to improve how players interact with the world, express progression, and access core features without unnecessary friction.

Server Infrastructure Upgrade

A major backend upgrade is underway. The server has been migrated from a limited hosted environment to a high-performance dedicated machine. This upgrade significantly increases available resources and is designed to support better overall performance, stability, and future player growth.

The new environment is currently running in admin-only mode while testing and refinement continue. The existing server will remain online for the time being to ensure a smooth transition.

Core System Improvements & Stability

A deep review of several core systems has been completed, focusing on long-standing edge cases and unintended behavior. These improvements are aimed at making gameplay interactions more consistent and reliable.

• Menus becoming stuck or failing to close
• Game modes opening or closing when they should not
• General flow and state handling across core systems

Players should experience smoother interactions and fewer unpredictable behaviors overall.

PA Menu (New Core System)

The PA Menu has been introduced: a highly customizable, full-screen menu accessible by parking your vehicle inside designated parking areas.

Designed as an intermediate system between the Quick Menu and the Safehouse, the PA Menu allows players to interact with most core systems without forcing a return to the safehouse, while also unlocking advanced functionality not available through the Quick Menu.

• Full Leaderboards
• Vehicle Management
• Player Management
• Races (coming soon)
• Crew Management (coming soon)
• Additional systems as they are introduced

This system significantly improves accessibility while preserving immersion and flow during gameplay.

Dynamic Scenario System

The PA Menu is part of a broader Dynamic Scenario System currently in development. This system allows for:

• Placement of custom ped and vehicle scenario pools
• Dynamic props and environmental setups across the map

The goal is to make areas feel alive and reactive, even when player populations are low, while enabling environmental storytelling, lore-driven locations, special builds representing famous teams, and easter eggs and narrative details.

The current open server will remain available as a free testing environment, where players can continue to spawn and experiment with cars freely.

The new server will introduce a full progression-based economy:

• Cars and tuning parts must be purchased
• Money is earned through races and time attacks
• Progression replaces free access with meaningful advancement

The safe house will be accessible as part of this experience and will serve as a central hub for progression systems.

Dealership System

A new dealership system is being introduced, launching with one physical location (with more planned in the future).

• A custom UI for browsing vehicles
• Sorting by brand, class, and vehicle
• Test driving cars before purchase
• Visual customization including paint color, rim color, interior color

The goal is a dealership experience that feels realistic, informative, and enjoyable.

Expanded Tuning Menu

A redesigned tuning menu will be accessible from inside the safe house.

• A refreshed UI
• A cart-based system for selecting parts
• A checkout process using in-game currency

This replaces the previous free-install model and ties vehicle upgrades directly into progression.

Progression Rewards

Progression now includes structured rewards. Reaching level milestones (such as level 10) will grant:

• In-game currency
• Unlockable cosmetic or progression-based items

This system provides clear incentives and long-term goals.

Polishing and integrating all these custom maps into GTAV is a significant challenge. Fortunately, most of the core areas have now been successfully placed and interconnected, forming a cohesive layout. The world already features a diverse range of environments, including urban areas, vast highways, technical touge routes, parking areas, and various circuits for racing/drifting. Most locations are currently accessible by driving, and our long-term objective is to achieve at least 90% seamless connectivity across the entire map. While the project is still far from complete, development is steady and continuous.

All maps have been fully converted and enhanced by us. This includes accurate rescaling, improved road surface smoothness where possible, optimized tons of collision, fully custom lighting setups, minimap, custom traffic paths with believable behavior, themed traffic variations, additional environmental detailing, and restoration of original animated textures.

For the public playtest, we have temporarily included additional separated touge locations to compensate for the fact that the primary "touge area" remains heavily work in progress. The currently available routes are: Sadamine, Irohazaka, Akagi, Nagao, and Happogahara.

Below is a simple image showcasing the current development status of the map:
