What's in the latest PUBG: BATTLEGROUNDS update?

Update 39.1 for PUBG: BATTLEGROUNDS, released December 4, 2025, transforms Erangel into a winter battleground (Erangel: Subzero) with snowfall, frozen rivers, and a Blue Zone that now imposes a freezing effect. A new tactical option, the BZ Grenade Launcher, alongside BZ Grenades, expands late‑game control and harassment tools. The patch also broadens content infrastructure, restoring UGC Alpha as a permanent feature with additional buildings, destructible objects, and seven new devices (Smoke Device, Light Device, AI Spawn/Navigation Devices, HUD Control Device, Vending Machine Device, Blue Chip Tower). In addition, the Weather system and visual effects shift across modes, with a focus on winter ambience in Arcade and general environmental updates. Full patch details are available in the official patch notes here, and the PC patch is live with console timing noted by the publisher here.

• UGC Alpha expansion: Permanently returns with more buildings, destructible objects, and new devices to craft creative modes.
• New items and gear: Ghillie Suit, EMT Gear, All-In-One Repair Kit, Tactical Pack, Self-AED, plus two new events for the Vehicle Spawn Device.
• Survivor Pass and War/World content: A new Survivor Pass with balance tweaks, plus ongoing Workshop and BALENCIAGA collaboration content.
• Casual mode and stats: Casual Play time limit increased to 60 minutes; Career/Stats UI tweaks to align Normal and Ranked views. See patch notes for full weapon balance changes and spawn/World map updates.
