Enhancement Passives

Upgrade Meta-System, Score Multiplier, Meta-Chip Multiplier, and Meta-Skill Uses in 13 Sentinels: Aegis Rim to unlock armaments and gain advantages.

Meta-System Level 2-10

Upgrading the meta-system level unlocks additional armaments and Meta-Skills. This upgrade is relatively cheap compared to other costs. You should aim to unlock additional Meta-System levels quickly, targeting at least level 8 within the first few waves and reaching level 10 by the end of the first area.

Score Multiplier x2-6

This passive ability increases your score. While not strictly necessary, score is used to obtain mystery points. Once all files are unlocked in the postgame, extra mystery points convert into meta-chips proportionally to your win streak length. If you aim to unlock every Mystery File without grinding points, you will need some Score Multiplier. A Score Multiplier of x3 is sufficient if you maintain a continuous win streak to the end. If you use the Recover button frequently, you may need to increase this multiplier further, depending on when and how often you recover.

Warning: The postgame in 13 Sentinels: Aegis Rim consists of 9999 battles and is a significant time investment, potentially much greater than the original game.

Meta-Chip Multiplier x1.2-2

This passive ability increases the Meta-Chips earned from battles. Invest in this upgrade early and often, and try to max it out as soon as possible. More chips allow for more of everything, and the upgrade quickly pays for itself. This multiplier does not apply to Meta-Chips earned from Remembrance.

Meta-Skill Uses 2-4

This upgrade raises the number of times you can use Meta-Skills. Extra Phase Plasma EMPs can trivialize most Area 1 waves, and having more uses is key to surviving later waves unscathed.
