Netmarble has added the 4th floor of the Battleground to RF ONLINE NEXT.

The 4th floor, 'Battleground: Orbital Defense Base', is accessible from level 85 and consists of four areas, including normal and high-tier zones. Players can obtain various grades of rare gear, materials, and hero-grade equipment.

In the high-tier zones, players can acquire unique collection items, the new 'Hot Pink Bunny' Rover costume, and the 'Snowflake' Rover costume. Four new bosses also provide high-grade rare gear, hero equipment and materials, the 8th active skill, and the blueprint for the MAU 'Thor'.

'Battleground 4th Floor: Orbital Defense Base' operates as an integrated battlefield alongside 'Battleground 3rd Floor: High Orbit Launcher Base'. It matches three servers within the same world, allowing a total of 600 players (200 per server) to participate.

On the 28th, the 5th floor of the Nemesis Secret Base will be expanded, allowing players to obtain the 'Launcher Chiron' blueprint and the passive skill 'Blood Frenzy'. On February 4th, the party dungeon 'Arcane Trial' will receive a 'Hell 1' difficulty setting, offering new items such as the 'Deep Space Stargazer'.

Additionally, updates include combat module expansions, three new hero-grade passive skills, a new category for guild research, and new Rover costumes. Furthermore, the new MAU 'Tempest', two new biosuit costumes, a 15-stage expansion for material conversion, and expanded core link categories will be added sequentially.

To celebrate the 300th day of RF ONLINE NEXT, events such as attendance bonuses, White Bear acquisition support, and the 'Conqueror of the Battlefield' event are being held, rewarding players with 'Kkot-soon-i' Rover summon tickets and White Bear part selection boxes.
