Hey fellow Cookie Run: Kingdom players! Can you believe 2025 is wrapping up? But Devsisters isn’t letting the year end quietly—they’re dropping "The Millenial Advent", the final major update of 2025! There’s so much fun stuff here, and I wanna break it down with you like we’re chatting in the guild chat. Let’s go!

The Millenial Advent

New Legendary In Town: Millennial Tree Cookie!

First off, the big star—Millennial Tree Cookie! He’s a Legendary, and he’s gonna fight as a Front-line Support. I know a lot of you were hoping he’d be a Bomber , but hey—Front Support might mix up our Arena teams in a cool way! Let’s test him out with our favorite Cookies once he’s here.

New Spots & Mystery Modes

①The Holiday Square: A brand-new area is coming to the kingdom… but here’s the thing—we don’t know exactly what it does yet! It’s a little surprise, but we’ll figure it out together when the update hits. Check out CRK The Holiday Square Answer to complete the detective event

②Town Square Arcade: Imagine hanging out in the Town Square and playing arcade games—sounds fun, right? No details on how it works yet, but it’s something to look forward to.

③Dinner Show: Players are already calling this "Masterchef for Cookies"! I bet it’s a chill mode about cooking or putting on a show—perfect for when you wanna take a break from raids.

 

Great Deep Sea War

Who’s been missing the Great Deep Sea War? Raise your hand! This fan-favorite mode is making its triumphant return, and we’re all hyped beyond belief. Round up your most powerful team, gear up, and get ready to dive headfirst into the fray—epic rewards are waiting, so let’s gooo!

Glorious Voyage

Glorious Voyage is a sea trade game mode in the v6.7 update, where players use a Ship's Wheel to start voyages, sail between islands with randomized goods prices to trade common and signature items, complete trade quests, and choose owned Cookies as captains for stat bonuses; they earn Trade Coins and Gold of Glory to redeem rewards in the shop, with extra seasonal ranking rewards up for grabs for top performers.

Cake Tower

Here’s a win we all love: Cake Tower is expanding! More floors, more challenges, and probably better rewards. Who doesn’t love climbing higher for goodies? Get ready to grind once the update goes live.

P.S.:The Resonants system is getting an update too, but we don’t have details yet. I’ll let you know when we do!

 

Wind Archer Cookie Crystal Jam

Wind Archer Cookie receives a significant power upgrade with his new Crystal Jam, "Last Gale". First, the Crystal Jam overhauls his core skill and grants him damage resistance right at the start of battles via the "Wind's Protection" buff. His Pursuer's Arrow also gets a major enhancement: the number of arrows fired during his transformation now scales with his attack speed boost, and each hit will deal area damage to nearby enemies—plus, the cooldown after using Pursuer's Arrow is shortened. When his Mighty Gale buff stacks to the maximum, he unlocks the "Howling Gust" buff, which further amplifies his output. Finally, the final shot of his Last Wind ability is replaced by "Last Gale," a piercing attack that blasts through enemy lines and triggers an "Afterstorm" effect; if Howling Gust is active when this happens, the Afterstorm will deal additional damage.

All these changes make Wind Archer far more versatile and impactful in both PvE and PvP content.

Tons of Costumes

Fashion lovers, rejoice… but check your rainbow cubes first. Here’s what’s coming:

2 New Legendary Costumes: Both look amazing—players are saying they’re "SICK." But warning—they’ll cost a lot of cubes, so start saving if you want them!

Special Costumes Rerunning: Missed limited-edition skins before? Now’s your chance to get them! Just don’t spend all your resources at once—plan wisely.

 

2025 Cookie of the Year!

Remember last year, Red Osmanthus Cookie won Cookie of the Year? Well, 2025’s vote is coming after the update! You’ll find the voting tab in the event section—start thinking about which Cookie deserves the crown. There’s also "Kingdom of the Year," but details are scarce for now.

Conclusion

All in all, "The Millenial Advent" update is a packed end to 2025 for CRK! There’s something for everyone—whether you’re excited to try the new Millennial Tree Cookie, grind the expanded Cake Tower, or chase those flashy new and rerun costumes. Sure, the return of the stock market sim is a bummer for some, and saving up rainbow cubes might feel tough, but the good stuff far outweighs the downsides.

Don’t forget to mark your calendar for the Cookie of the Year vote and brush up on the Abyss of the Four tips to hit the ground running. Let’s make the most of this final big update of 2025—see you in the kingdom!
