The new set of ” K.O. Coliseum ” has finally begun!

With the ” power-up” system as the centerpiece and role renewal, the range of configurations is wider than ever, and each match is filled with the excitement of new discoveries.
Understanding each champion has become even more important, and a challenging environment has arrived where knowledge and experience can be put to use.

The augments have been significantly updated, and there are many unique features such as “Solo Leveling” and “Tale of 7”, which are just like event modes!
While the initial environment will be somewhat chaotic, the search for configurations and trial-and-error in play will definitely be a fun period anyway!
