A new event page appeared on the official KR website that features all the NIKKEs available in the game on release (or maybe some will appear soon after on a banner). There are many characters that weren't available in the CBT or TT, so now is your chance to check their basic information and shooting poses!
You can find the website here:
Simply click on any of the cards there and a popup will appear that shows some of the details and the shooting animation.
PS. We are hoping that a similar event will soon appear for the Global players.
PS. 2. We will add the missing characters soon to our website.
