Best ACs to Clear the Arena With

Use ACs with Treads

original (17).jpg

In the Arena, battles are one-on-one, and you cannot use repair kits. Therefore, it is recommended to use Tank-type ACs that can combine high firepower and high durability in these battles.

Arena Rewards

Winning Arena Matches Gives You OST Chips

original (18).jpg

Clearing the Arena allows you to obtain OST chips required for OS tuning. With OS tuning, you can enhance your OS by increasing repair kit effectiveness and reducing damage taken. It's recommended to gradually work on these enhancements as they become available.

Access Enemy's AC Preset Data

original (19).jpg

Once you defeat an enemy AC in the arena, its preset data becomes available. If you have the parts required by the preset data, then you can build ACs just like the ones you fought.

Get Emblems

original (20).jpg

Clearing the Arena allows you to obtain emblems. While they don't affect your AC's performance, you can attach them to your AC as bling.
