Kaiju No. 8 THE GAME has launched a half-anniversary event that adds new story content, playable characters and large-scale in-game rewards, publisher Akatsuki Games announced Monday.

The free-to-play action RPG, co-produced by Akatsuki Games Inc., TOHO Co., Ltd. and Production I.G, is marking six months since launch with a limited-time campaign that includes daily free gacha pulls, login bonuses and new story chapters. According to the developers, players can earn up to 30,000 Dimensional Crystals through event rewards and special missions during the celebration period.

The update introduces Main Story Chapter 8, titled “Plan D,” which advances the narrative beyond the Dimensional Gate and into a new setting described as a frozen parallel version of Dubai. The chapter centers on Sagan Shinomiya, who faces a new threat, Dimensional Identified Kaiju No. 6, while attempting to protect her squad and secure a route home. The new chapter is available now to players who have progressed far enough in the main campaign.

Alongside the story expansion, the half-anniversary event features a daily gacha promotion offering eight free pulls per day, for a total of up to 80 pulls over the course of the campaign. Akatsuki Games said the promotion is designed to give players additional chances to expand their rosters without spending premium currency.

A new five-star playable character, [Over Limit] Sagan Shinomiya, also joins the lineup as part of the update. The character uses a spear-based weapon configuration known as Mode: Lance, a form that emphasizes high-risk, high-damage play by pushing the character beyond normal limits. A corresponding five-star spear weapon, Lc-Anorollal, is being introduced through a pickup gacha.

The celebration additionally includes the return of a pickup gacha featuring Soshiro Hoshina, as well as a paid-only gacha that guarantees at least one five-star blunt-type character. As with other gacha offerings, availability and conditions vary by banner.

Kaiju No. 8 THE GAME is available on iOS, Android and Steam, with support for multiple languages and optional in-app purchases. The half-anniversary campaign is live now, with full details available through the game’s official channels.
