What is Galactic Disaster?
A Season-Exclusive Large Event
The Galactic Disaster is a large-scale event that takes place over 9 weeks and features various content such as Missions, exclusive Chaos, high-difficulty boss battles, and score attacks.
Galactic Disaster Season 1 Forbidden CatalystUpdated Every 3 Weeks
The Galactic Disaster is divided into three periods, each lasting three weeks. Each time the period changes, new Missions will be added and content will be unlocked.
Exclusive Chaos Appears
An exclusive Season Chaos appears in the Galactic Disaster. In Season Chaos, you can obtain exclusive equipment and Cards and create Save Data separate from the normal Chaos.
Season Save Data is Required
For some content in the Galactic Disaster, normal Save Data cannot be used. You can only use Save Data created in Season Chaos.
Season 1 Forbidden CatalystGalactic Disaster Walkthrough
Progress Through the Missions First
The Galactic Disaster is a Mission-based event. Progressing through the Missions unlocks the Season Chaos Challenges, so be sure to clear them first.
Create Save Data in Season Chaos
Once Season Chaos is unlocked, repeat the Challenges to create your Save Data. Only the Save Data created here can be used in the high-difficulty content within the Galactic Disaster.
Be Sure to Clear It at Least Once
If you don't clear the Season Chaos, some content will remain locked. Simply escaping repeatedly to create Save Data isn't effective, so make sure to clear it at least once.
Nebula Distortion Challenge
Nebula Distortion is a boss battle that uses Season Save Data. In addition to the difficulty level, various restrictions can be added. Clearing the battle with more restrictions applied will grant you more achievement rewards, so aim for the highest difficulty you can handle.
Challenge the Great Rift
The Great Rift is a score attack that uses Season Save Data. In addition to score achievement rewards, there are also cumulative score rewards, so challenge it repeatedly to secure the rewards.
*The Great Rift will be unlocked midway through the event period.
Exchange Rewards at the Supply Shop
Once you've obtained rewards from each content, exchange them for items at the Supply Shop. In the shop that unlocks in the latter half of the event, even Limit Break materials for 5-star characters are available.
Galactic Disaster Event Farming Priority
Prioritize Season Chaos
While the Galactic Disaster is ongoing, it's generally recommended to grind Season Chaos. As some content requires Season Save Data, it's important to create a powerful Save Data in Season Chaos.
Season Chaos Will Become Permanent
Season Chaos will be added as permanent content after the Galactic Disaster ends. This means it's not a limited-time opportunity, so if you've already created a powerful Save Data, there's no need to grind excessively.
Achieve a Score of 8,000 Every Week
Season Chaos features score-based achievements, and rewards are available weekly. Use these achievement scores as a benchmark and grind Season Chaos each week.
Progress the Chaos Matrix
The Zero System's Chaos Matrix offers limited-time rewards, and you can also make progress on it during the Galactic Disaster. Since you can obtain Chaos Orbs in Season Chaos, it's generally better to prioritize this mode.
