Line Games announced on October 8 that its open-world MMORPG Uncharted Waters Origin, co-developed with Motif and Koei Tecmo Games and serviced in-house, has launched a collaborative event with The War of Genesis. Through this collaboration, Haidelun, an Outer World character from The War of Genesis, has arrived in Uncharted Waters Origin as a brand-new admiral. The new admiral Haidelun is an S-tier admiral specialized in combat and bombardment, added independently without a separate admiral chronicle.

Previously released collaboration admirals, navigators, and exclusive equipment from The War of Genesis are also making a return. The returning admirals include the Black Prince and Iolin Pendragon, while returning navigators feature G.S, Robin, Karls, Kuhn, Ophelia, Sarah, Crow, Hayabell, Kaza, and Elizabeth. Alongside them, a free navigator named Kalix has been introduced. Kalix is an S-tier navigator specialized in trade content, possessing various abilities to assist with efficient trading.

An update has also landed for the navigator content known as the Affinity Chronicle. The protagonist of this affinity chronicle is Aurelie, and players can experience stories detailing the narratives of related navigators such as Kalix, Linus Ratchet, and Chevalier Rump, while earning exclusive equipment rewards. Beyond that, system improvements have been rolled out to enhance user convenience and adjust balance. The free usage count for general and consecutive battles has been unified to 150 times per day, after which combat can be sustained by consuming Action Power.

In addition, the UI for religion and tax-free areas as well as the UX for guild synthesis have been refined, with a 'Claim All' feature for daily tasks and an auto-enhancement separation function added into the mix. The maximum score for advanced salvage has been bumped up to 150,000 points, further polishing overall sailing convenience. Hand in hand with these updates, a generous reward event is scheduled to run until November 10. First off, a 14-day attendance event dishes out various goodies such as the in-game currency Blue Gems, enhancers, and equipment/parts request forms, while certain missions also yield Silver Bullets needed for event battles.

A The War of Genesis collaboration event is also underway. Players can log in for 7 days, complete missions structured as a trade content guide to snag rewards, and make use of an exclusive event shop. On top of that, four event scenarios revolving around a case involving a werewolf and two adventure notebooks (Legend of the Valley, Pack of the Valley) are ready to play. Event battles feature permanent event monsters ranging from level 50 all the way up to stage 115. Each battle consumes 1 Silver Bullet, and depending on the difficulty, the acquisition amount of Grey Tokens usable at the event shop increases.

Events tied to special trade are lined up as well. Content for silver bar barter and acquiring high-grade silver makes a comeback, and the food pandemic market prices get a boost. A production route has been added where silver scraps and iron ore are fashioned into silver gun barrels, which are then processed into the brand-new trade good, silver matchlocks. Furthermore, depending on the cumulative net profit of silver bars, players can claim silver scraps as rewards, which can then be put to work in producing silver gun barrels. On top of all that, competitive battles with varying trade conditions each week will unfold over the course of five weeks. Finally, rewards are up for grabs across various event shops, including a dedicated shop for Grey Tokens acquired in event battles, alongside Halloween and The War of Genesis collaboration themes.
