PUBG Mobile KR has released its 3.9 update. It includes an enormous Transformers crossover from July 8 to September 2. Users can bring Optimus Prime and Megatron into the game. This will ensure legendary battles in classic Battle Royale.
Transformers Mode: Autobots vs. Decepticons
This update adds a new Transformers mode. Erangel is where players can enable Spacebridge Beacons. That calls forth either Optimus Prime or Megatron, these robots will be able to transform into vehicle and robot modes. Optimus has an axe, and Megatron has a cannon. But both are special powers for your team.

The patch overhauls parts of Erangel. There are Neon Outposts and Astro Dens for players to discover. These areas have loot and tactical cover. New Transformers-inspired vehicles that can be ridden come with the update. Consider Mega Trucks and Electromagnetic Tanks. PUBG includes hoverboards for quick travel as well.
New Weapons and Attachments
Classic Mode receives new equipment as well. The ASM Abakan rifle makes its debut and has single, burst, and auto-fire support. The damage and stability are improved with a new sniper barrel extender. In addition, attachments now enhance reloads and recoil.
Zombie Uprising 2.0 is back in Metro Royale. Prepare for harder battles and improved rewards. The mode now drops genetic codes to spawn stronger monsters. Ranked Arena comes back with polished mechanics.
Social Hub: A 3D Lobby Experience
