Nimble Neuron, a subsidiary of Neptune and the developer of the PC title 'Eternal Return', has kicked off the preseason for Season 12. The theme for this season is 'Sailing'. To match the summer season, Nimble Neuron is introducing swimsuit-themed skins along with various content and system improvements. Players can experience the new content and changes that will be applied to the regular season during the preseason, which runs until August 12.

In preparation for the regular season starting on August 13, a Season Pack will be available. The Season Pack includes the special edition Hero-grade skin 'Blue Wave Shuirin', along with 6 skins and 2 characters. Additionally, the ER Pass will be available, featuring the 'Glass Wave Tazia', 'Signpost on the Waves Yumin', and 'Water Attribute Nia' skins.

In terms of game content, 'Subject Observation Logs' have been added, allowing players to check the individual stories of each character. Players can sequentially unlock character reports and observation logs by playing the game. The safety zone system in the late game has been changed to a 'Multi-Chrono Sphere' to support more strategic gameplay. Furthermore, several weapon skills have been improved, 4 new item skills have been added, and the rest and recovery mechanics have been adjusted.

Nimble Neuron CEO Kim Seung-hoo stated, "We have prepared refreshing content, updates, and special events to ensure everyone can enjoy a cooler summer with Season 12," adding, "We will always do our absolute best to repay the players who continue to show their affection and support for the game."
