This update was released on July 10, 2025. Season pass holders can unlock the full content, including two new maps, three exclusive vehicles, and an expert character. All players get two new wheeled drones, a truck paint system, and deep gameplay optimizations for free.
I. New Maps and Environmental Challenges: Dynamic Melting Snow and Underground Exploration
Transylvanian Alps Dual-Map Architecture
Two new open-world maps have been added, with the core environmental dynamics centered around spring snowmelt: players must deal with continuously changing muddy terrain, collapsing ice riverbanks, and temporary waterways formed by melted snow, adjusting tire pressure and driving strategies in real-time.
A multi-level cave system is introduced for the first time, featuring narrow passages and large caverns that require lighting equipment and winch cooperation to traverse. Ancient civilization relics are hidden within the caves, linked through 16 expedition missions, 13 contracts, and 8 scientific research objectives.
Environmental Interaction Upgrades
Friction Physics Engine Redesign: Traction calculations for rocks, wet mud, and partially melted snow are closer to reality. Lightweight vehicles are prone to getting stuck in soft mud, while heavy trucks need to guard against side-slipping on slopes.
Radar Power Dependency: The exploration radar consumes vehicle power, requiring players to balance drone deployment, equipment power, and engine load. Strategic energy management becomes crucial for survival.
II. New Vehicles and Expert System
Three Terrain-Specialized Vehicles
TUZ 302 Capricorn: A high-speed reconnaissance vehicle equipped with low-resistance tires and a lightweight chassis, specialized for forward scouting and path planning.
Haukka NS-420: An experimental trailblazing vehicle with an active track adjustment system, capable of opening up off-road shortcuts where conventional trucks cannot pass.
KRS 63 Pathfinder: A heavy-duty mud and snow breaker with extra-wide tires and a high-torque engine designed for deep mud and melting snow areas, capable of towing multiple stuck vehicles.
Expert Character Synergy Bonuses
Technician Thomas Stevenson: Passively reduces power consumption of drones and add-ons by 30%, alleviating the energy pressure on radar systems.
Manager Henry McCall: Increases mission fund earnings by 20% and unlocks hidden treasure items during relic exploration.
III. New Drones and Toolbox Expansions
Free Wheeled Drone Deployment
4-NCR Anchor Drone: Can be fixed to rock walls or tree trunks as a winch anchor point, solving the problem of being stuck in terrain without anchor points.
SCT-6 Reconnaissance Drone: Creates a temporary network coverage area with a 50-meter radius, enhancing the signal strength and control range of other drones, especially useful for cave exploration.
Toolchain Synergy Optimization
Drones can now directly deliver supplies from the truck's cargo hold without unloading.
When a vehicle overturns, drones and some lightweight vehicle engines do not automatically shut off, retaining emergency escape capabilities.
IV. Game System Optimization: Collaboration, Customization, and Experience Innovation
Cooperative Mode Restructuring
Flexible Progress Sharing: Teammates can use the host's funds to build facilities or modules, and all team members can independently earn mission progress.
Radial Menu Enhancement: Added three location marker commands (SOS, resource point, danger zone), optimizing the winch target selection logic for controllers.
Full Truck Paint System
Open hue, saturation, and brightness adjustments, supporting personalized color schemes for the entire fleet, with paint schemes synchronized in real-time to cooperative mode.
Interface and Operation Flow Upgrade
Redesigned base module UI, adding task truck tow markers and "New" tags for newly unlocked vehicles.
The pause menu can be accessed at any time from the headquarters interface, allowing players to check the codex or adjust settings without interrupting exploration.
V. Critical Bug Fixes and Performance Improvements
Fixed the issue of frame rate drops in the Eastern Beskids map, optimized the efficiency of custom interface module switching. Resolved graphical errors such as low-resolution rock textures and HUD disappearing when recovering flying drones.
Corrected soft lock issues with anchor point deployment, abnormal binocular mission icon display, and wheeled drones dragging instead of teleporting in evacuation zones. Adjusted engine torque parameters to ensure power output matches physical expectations when pulling heavy loads.
Finally, if you often experience lag during updates, you can use the biubiu accelerator. Not only does it download quickly without wasting time, but as a thank you to new and old users, there's a limited-time promotion. Starting now, users can enter the exclusive redemption code [biubiu no drop] through the official designated channel to immediately activate 72 hours of premium membership. Combined with the 24 hours obtained from the first registration, you can get a total of 96 hours.
In summary, this update coincides with the Steam Summer Sale, providing a chance for multi-platform players to return to the off-road adventure. "Ice Coast" enhances the core experience of "Expedition: Mudrunner" from basic transportation to strategic scientific exploration through environmental dynamism, equipment specialization, and cooperative freedom. If future updates in the fourth season further integrate geological survey gameplay (such as rock layer sampling and analysis) or dynamic weather disasters (avalanches, ice floods), it will likely solidify the game's position as a technical benchmark in the realistic off-road genre.
