What's Included

This comprehensive tunnel MLO delivers a fully realized underground passage with authentic architectural details. You get a long, wide main tunnel with proper road markings, emergency lighting systems, ventilation shafts, maintenance access doors, and security checkpoints. The interior includes side passages for pedestrian access, equipment rooms, control stations, and connection points that allow integration with other MLOs or custom mapping projects. High-quality textures and optimized geometry ensure smooth performance even during high-speed pursuits.

Key Features

• Massive Scale - Extensive tunnel network with multiple lanes supporting high-speed vehicle traffic in both directions
• Realistic Architecture - Authentic tunnel design with proper support structures, lighting arrays, and safety systems
• Multiple Access Points - Several entry/exit ramps connecting to surface roads for flexible routing options
• Emergency Systems - Functioning emergency lighting, fire suppression props, and evacuation signage for realism
• Maintenance Areas - Side rooms and access tunnels for utility workers, security, or hidden operations
• Custom Lighting - Atmospheric tunnel lighting with emergency backup zones and dark sections for dramatic effect
• Vehicle Optimized - Wide lanes and smooth surfaces designed for high-speed driving without collision issues
• Performance Efficient - Optimized LODs and culling ensure minimal impact on server FPS

Perfect For

• Illegal street racing events with underground circuits
• Smuggling operations moving contraband beneath the city
• Police pursuits with dramatic tunnel chase sequences
• Secret government facilities hidden underground
• Emergency evacuation routes during disaster roleplay
• Gang territory control battles in neutral underground zones
• Maintenance worker jobs for infrastructure roleplay
• Horror events with dark, atmospheric tunnel sections

Layout and Design

The tunnel features a main passage with multiple vehicle lanes separated by center barriers, mimicking real-world highway tunnels. Wall-mounted lighting provides consistent illumination while creating dramatic shadows in certain sections. Side passages branch off to maintenance rooms, ventilation shafts, and emergency exits. Control rooms near access points house security equipment and utility controls. The architectural design balances realism with gameplay needs - wide enough for multi-vehicle racing but confined enough to create tension during pursuits.

Installation

1. Download the Grand Tunnel MLO and extract to your server resources folder
2. Add the resource to your server.cfg and ensure proper load order after game files
3. Review the included coordinates document to understand entrance/exit locations
4. Configure any door locks or security systems for maintenance access areas
5. Test vehicle handling and collision throughout the tunnel length
6. Adjust lighting settings if needed to match your server's visual style

Framework Compatibility

• ✅ ESX Legacy - Compatible with all ESX job scripts for tunnel maintenance roles
• ✅ QBCore - Works with QBCore gang systems for territory control
• ✅ Standalone - Pure MLO, no framework dependencies required
• ✅ Universal MLO - Compatible with any FiveM server regardless of framework

Roleplay Scenarios

This tunnel enables diverse roleplay opportunities across multiple server types. Racing servers can create underground time trial courses with checkpoints through different sections. Criminal organizations can establish smuggling routes where shipments move through the tunnel undetected by surface patrols. Law enforcement can stage dramatic pursuits that transition from surface streets into the confined tunnel environment. Infrastructure workers can perform maintenance roleplay, inspecting systems and responding to emergency situations. The atmospheric environment even supports horror events where players navigate dark sections with limited visibility.

What Makes It Stand Out

Unlike simple tunnel props or basic underground passages, this Grand Tunnel delivers a fully realized subterranean environment with professional attention to detail. The scale is impressive - long enough to enable high-speed racing sections while including slower zones with tighter turns. Realistic architectural elements like ventilation shafts, cable trays, and emergency equipment add authenticity. The lighting design creates atmosphere without sacrificing visibility for gameplay. Multiple access points provide strategic options for pursuits and escapes rather than simple point-to-point routing.

Integration with Existing Map

The tunnel is designed to integrate seamlessly with Los Santos' existing road network. Entrance and exit ramps connect to major highways and surface streets at logical locations. The underground route provides an alternative path for cross-city travel, creating tactical options during pursuits or time-sensitive deliveries. You can position the tunnel to connect different neighborhoods, bypass congested areas, or create shortcuts for those who know the underground network. The design accommodates both standalone use and integration with additional custom mapping.

Technical Specifications

• Interior Type: MLO with exterior integration points
• Total Length: Extensive multi-section tunnel network
• Lane Width: Multi-lane highway standard with emergency shoulders
• File Size: Approximately 120MB
• Performance: Optimized with LODs and culling zones
• Collision: Full vehicle and pedestrian collision throughout
• Lighting: Custom tunnel lighting with emergency backup zones

Customization Possibilities

Modify the tunnel to fit your server's specific needs. Add security checkpoints with gates and guard stations for controlled access. Place custom props to create construction zones, accident scenes, or blockades for events. Configure lighting zones - illuminate high-security sections while keeping criminal areas dark. Install custom signage directing to different destinations or marking territory boundaries. The spacious design accommodates additional props without feeling cluttered, allowing creative customization while maintaining the core functionality.

Event Potential

Host memorable server events using the tunnel as a dramatic venue. Organize underground racing tournaments with timed sections and leaderboards. Stage heist scenarios where criminals must navigate the tunnel while evading police blockades at exits. Create disaster response events where emergency services evacuate civilians through the tunnel network. The unique environment provides an engaging alternative to standard city streets, making events feel special and attracting player participation.
