Sardinium Is For Unlocking Upgrades

Upgrade Points Are For Activating Effects
Upgrade Points are consumed to activate the effect unlocked by the Sardinium. There are many ways to get this if you are playing Hero Mode.
Hero Gear Recommended Upgrades
Recommended Upgrade Path
Upgrade Details
| Order | Upgrade | Used Sardinium |
|---|---|---|
| ① | Smallfry HP Up | 1 |
| ② | Better Hero Shot Upgrade before fighting the boss at site 2 is recommended. | 1 |
| ③ | Special Charge Up | - |
| ④ | Ink-Tank Capacity Up | - |
| ⑤ | Suit Recovery Up | 3 |
| ⑥ | Smallfry Ink Saver | 3 |
| ⑦ | Ink-Tank Capacity Up | 1 |
| ⑧ | Ink Resistance Up | - |
| ⑨ | Better Hero Shot | 4 |
This Hero Gear upgrade path can allow you to defeat the last boss without making too many detours while taking the necessary upgrades. The main focus of this build is to strengthen your shooter and minimizing the consumption of Sardinium which is difficult to obtain.
Focus Hero Shooter Upgrade Early
The Hero Mode Bosses in Site 3 are much stronger than those in Site 1 and Site 2. With an unupgraded gear, it will be difficult to fight because of the slow fire rate. Focus on upgrading this before you challenge the boss fight at site 2.
High Priority Upgrades
| Better Hero Shot | |
|---|---|
| ・Hero Shooter's rate of fire is increased. ・Can be upgraded twice. |
| Ink-Tank Capacity Up | |
| ・Hero Shooter's rate of fire is increased. ・Can be upgraded twice. |
| Suit Recovery Up | |
| ・Increases the recovery of broken suits. ・Can be upgraded twice. |
The upgrades that should be prioritized on Hero Gear should be those that can improve your weapon and HP. The Hero Shooter will be used until the end and the difference in performance between the unupgraded version and the upgraded version is very drastic. Also, since the Hero Shooter makes you vulnerable to enemy attacks, the Suit Recovery upgrade should also be a priority.
Upgrades That Are Needed Later
| Smallfry HP Up / Smallfry Ink Saver | |
|---|---|
| Increases the durability |
| Reduces the ink consumed |
In the final stages of Hero Mode, there is a stage where you will need Smallfry Upgrades. If they are not upgraded, you will be killed immediately which will make the progress very difficult. It is highly recommended that you upgrade these while upgrading your shooter.
Smallfry Upgrades That Are Not Required
| 【Smallfry Quickrespawn】 Shortens the respawn time of Smallfry |
| 【Smallfry Damage Up】 Smallfry deals more damage against enemies |
Although it can strengthen Smallfry, it requires a lot of Sardinium to upgrade these. If you have extra Sardinium, it can help you get stronger but it is not required.
Upgrade Reset After Clearing
Materials Can Be Left Unused
After clearing the game, a Hero Gear reset option is added from the Gear Upgrade screen. This option allows you to start over from scratch while keeping the Sardinium and Upgrade Points that you have used. Although it only has a little effect, it makes it possible to challenge all stages with unupgraded gear.
