Fortress of White Night

Step into the snow, and find out the unexpected answers that await you!

Fortress of White Night Letter

Greetings Agents,


We are the game developers of Closers.


We would like to take this opportunity to thank you for your patience and support throughout Season 3 of Closers, which has officially come to an end with this update.


From <Season 1: Humans vs Dimensional Monsters>,
to <Season 2: Humans vs Humans>,
and to <Season 3: Closers vs Closers>.


Your love and support made it possible for all these stories to begin and reach the conclusion.
Agents, we sincerely appreciate it.


This concludes the story of how the young people who formerly defended the small city of <New Seoul> became the courageous Closers who protects the world.
We hope that the story will leave all of the agents with pleasant recollections.


We would like to inform you that all of these stories were only <Closers – Part 1>.
We promise to learn from our successes and mistakes to give more meaningful and genuine stories to everyone.
The countless Closers stories are something we hope you look forward to.


But before we proceed, we have a favor to ask of you.
Many secrets will be revealed in the third season’s new and last area, <Fortress of White Night>.


Therefore, for the time being, we kindly ask that you avoid from exposing any <Fortress of White Night> spoilers.


For the Closers who have finished Season 3, we have prepared a special reward called
the <Memorial Box of White Night> to show our appreciation and support.


Here is the list of the rewards:

x1 New Accessory

  • You can obtain the reward for each character by completing the story.
  • Image can be equipped.

x1 Effect Costume (Phase Wings)

  • Available for a limited period only till February 22, 2023 maintenance
     Can not be obtained after February 22nd, 2023 maintenance 
  • You can claim the reward for each character after completing the story to get this item.


We’ve thought a lot about how we can offer this reward, and we’ve concluded that it needs to be [obtained by completing the story] because it is closely tied to the storyline.


We hope that you enjoy the final story of Season 3 that we’ve poured our hearts into, as well as receive the special rewards!


Season 3 is over, but Closers’ story is just getting started.
There are still a lot of Closers-related stories to be told.
We’d like to introduce the forthcoming features that we are working on before we start <Closers – Part 2>.


[New System]
We’re getting ready to update a system that will utilize the content from <Fortress of White Night> so stay tuned for that.


[Closers – Part 2]
<Back to Everyday Life>
The theme for Season 4 is <Back to Everyday Life>.
We’d like to tell you the story of Closers who had no alternative but to disregard their daily lives due to confrontations with formidable foes.


However, they still fight evil in their daily lives.
Season 4 will include a furious conflict between the Closers who want to safeguard their ordinary lives and the enemies who want to destroy them.


Additionally, we intend to improve Closers by utilizing more unique and diversified ideas in terms of tale structure and presentation.
We sincerely hope you will anticipate it.


We made it this far because of the support from all agents.
As the developer who completed <Closers– Part 1> this year, my heart is brimming with happiness.


We’ve been able to get this far thanks to your love and interest for Closers, as well as your encouragement and support.
We want to express our sincere gratitude to you once more.


We will always be grateful for your love and encouragement, and we will work hard to keep getting better.
We hope you’ll keep anticipating Closers’ never-ending adventures.
Thank you very much.


The developers of Closers
