Event Overview

Progress through Main Story Chapter 4 and challenge the Score Battles to earn rewards such as Dimensional Crystals and an event-limited weapon.

■ New ★4 Weapon

AR-Hound 64 (Assault Rifle)

■ Score Battle

During the event, you can challenge score battles of varying difficulties.

These battles do not consume Stamina and are unlocked by progressing through the new Main Story chapter.

Please check the event screen for the specific unlock conditions for each difficulty.

In score battles, your performance is evaluated and scored based on three criteria: total DMG taken until victory, number of rounds elapsed at victory, and number of Core Exposures. Scores are ranked from C, B, A, to S. (No score will be awarded for a defeat.)

The highest achievable score is 300,000, with the breakdown for each criterion as follows:

・Up to 130,000 for total DMG taken

・Up to 120,000 for the number of rounds elapsed

・Up to 50,000 for Core Exposures

There are two types of rewards related to score battles: first-clear rewards and mission rewards, which are earned by achieving a certain score.

Main Story Chapter 4 Release Celebration Login Bonus

Log in during the period to get up to 10 Pickup Gacha Tickets.
