| Firn Night |
A.K.A. "Project Babel: Aurora Sky", occurred under the Firn Night Patch.
1. The Project Babel - Aurora Sky consists of 3 levels. Each level has only 1 optional stage. In the optional stage, you can freely choose the combination of strategic objectives.
2. Each level can be challenged with up to 3 teams. You can only use the 1st team to attempt each level at the beginning. When the 1st team has a clear reward for each level, the 3rd team will be unlocked. When the 2nd has a clear record for each level, the 3rd team will be unlocked. The record of each team's challenge level and members will be saved separately.
3. Each level contains 5 difficulty levels. Based on your selection, the final Strategic Level will gain different bonuses. Final Strategic Level = Strategic Level Selected x Difficulty Bonus Coefficient (rounded off).
4. There are three parts in the level: [Environmental Intelligence], [Strategic Target] and [Support Module] which will affect the battle.
5. After each successful challenge, the members used will be locked and cannot be used in other levels and form another team. The players can change the status of the members by "Clearing Record" or "Restoring Record".
6. According to the combination of Strategic Objectives selected in the challenge of each level, rewards can be obtained once the total Strategic Level for a single level or the accumulated Strategic Level has reached the requirement of the Challenge Mission.
7. Once you complete a level, you will get a collectible reward. The higher the Strategic Level you reach, the better quality the collectible will be.
8. The final Strategic Level reached by all of your teams will be shown on the Babel Tower Ranking.
