Netmarble has launched a major update for RF Online Next featuring the introduction of Albern Fortress, the game's first Outer Planet Siege Warfare. The update also brings a new server and an overhauled marketplace system to the title.

These changes expand the competitive landscape for guilds while restructuring core game economies through a unified marketplace. The update aims to deepen endgame engagement through large-scale player-versus-player content and seasonal limited-time events.
Siege warfare involves 10 guilds comprising 500 players, with winners requiring a 20-minute hold time on the Control Bridge. The update also features a Halloween dungeon consisting of 8 distinct stages.

Season Trajectory
This update fundamentally shifts the competitive meta for RF Online Next by institutionalizing large-scale guild warfare. It moves the game away from smaller individual encounters toward a system that favors organized, high-stakes territorial control.
Players on the new Vera server will have until November 11 to utilize growth support events to catch up. Guild leaders must prioritize winning Mining Wars or auctioning Alberium Ingots to qualify for the inaugural October 31 siege.
The takeaway
Players looking to participate in the Albern Fortress sieges should focus on coordinating guild strategy to hold the Control Bridge for the required duration. Monitoring the new marketplace unification will be essential for managing in-game assets effectively during this transition.
