Toho has announced a special Earth's Ultimate Showdown collaboration between the film "Godzilla vs. Kong" and the mobile game "Godzilla Battle Line," which was released June 15.

The Earth's Ultimate Showdown event will be held on the launched mobile game "Godzilla Battle Line" on July 1.

In the game, Kong, as seen in the film "Godzilla vs. Kong," is introduced as a new battle piece. Kong's battle piece can be earned by clearing missions or exploring Expedition Maps that can be won in ranked battles. The probability of discovering Kong differs for each Expedition Map. Kong is a heavyweight ranged attacker who uses his monstrous strength to sweep through waves of units as he advances. When serving as the team's leader, Kong can perform a special move called "Earth Break," damaging a circular area and increasing damage dealt by allied units by 20 percent for 15 seconds.

Players can purchase a collab package, "Skull Island Expedition Map," which increases their chances of discovering Kong in the area. Players can earn titles and collab icons for a limited time by clearing special missions during the limited event period. During this period, Skull Island will be available during specific times of the day and Kong will make a special appearance as the third force to raise the battle a few levels.

Kong will only be available for a limited time, but Kong can be used beyond the event period once obtained. In addition, players who purchase the premium Godzilla Pass can earn collab icons, titles, and battle pieces as premium rewards, in addition to the regular grade rewards.
