IGG announced on the 6th that its title, Doomsday: Last Survivors, is launching a collaboration with the anime 'Fairy Tail'. Fairy Tail is a fantasy series that depicts the adventures and journeys of mages from the Fairy Tail guild, and it is beloved by fans worldwide for its unique characters and high-octane combat.

This collaboration centers on the 'Otherworld Grand Magic Games' event. The update introduces a variety of content, including the Games Conquest, Special Training Camp, Guild Missions, Star of the Games, and the Grand Magic Games. Additionally, it features collaboration items and events themed after Fairy Tail characters. In the Games Conquest, which runs until the 30th, players can use 'Games Bullets' to challenge zombies across 10 floors of the Empire Tower. Each successful hit grants a random reward, and there is a chance for Erza Scarlet to appear.
