PUBG Mobile 3.8 Beta Brings Steampunk Frontier Mode with Trains, Hooks & Giant Serums

Tencent has officially unveiled the first details of the upcoming PUBG Mobile 3.8 update, and it’s bringing a bold new flavor to the battlefields. Titled “Steampunk Frontier,” this update injects steampunk fantasy into the classic Erangel map, introducing new traversal mechanics, themed locations, and wild gear. The first Beta Phase went live on April 3, 2025, and here’s everything you need to know.

🔧 Steampunk Frontier Mode Overview

At the heart of the update is the all-new Steampunk Frontier mode — a stylized twist on traditional gameplay that transforms classic zones into industrial train hubs and mechanized strongholds. Here are the main features:

• Aetherholm: A massive central train station with a clock tower, elevators, and a hidden room packed with loot.
• Cargo Hub: A dual-zone transit area connecting urban and rural parts of the map via railways.
• Hot Air Balloons: Floating platforms scattered across the map for quick recon or surprise attacks.
• Rollercoaster Checkpoint: A high-speed ride that doubles as a fun set piece and a tactical vantage point.

🚂 Train-Based Gameplay Mechanics

Movement is about to get more exciting with steam-powered locomotives that do more than just look cool. They’re packed with loot and serve as mobile hotspots for combat:
