Project Clean Earth Guide

Most players might give up the game very early before they finish chapter 27.
Here is a preview about what will happen once the player gets through chapter 27.

Why chapter 27

You can unlock the High-Tech Chipset after chapter 27.
For normal Chipset, you can bring 10 normal Chipsets to game stages.
While for High-Tech Chipset, you can bring at most 3 High-Tech Chipsets game stage.
However, 2nd and 3rd slots will only be unlocked after you win more chapters.
In short, you can bring 10 normal Chipsets and 1 High-Tech Chipset right after chapter 27. The extra High-Tech Chipset makes it easier and faster in Gem Farming.
Please visit Gem Farming for more detail.

You are required to use 4000 gems to purchase 5 High-Tech Chipsets.
4000 gems in exchange for 5 High-Tech Chipsets

How to beat chapter 27

If you have trouble beating chapter 27. Here are some suggestions which help you.

1. Move Speed + High Evasion Rate

It is advised to upgrade Build Body to BN Unit-5, BN Unit-5 gives you Move Speed +5%.
High Evasion Rate can be gained by equipping the Vibrating Module.
If you use circular movement to round the enemies, for example, using Plasma Field or Turrets, you would better raise your Move Speed as some enemies match your normal Move Speed. Move Speed +5% will get great help in game stages.

2. High Defence

Some enemies will crash into you and deal great damage. High defense can boost your survival rate.
Equipping the Polymer Armor will help a lot.

3. Use different movement

Since you want to avoid some enemies which crash into you at a very high speed, sometimes circular movement is not helping you at all.
You can use S-shaped or Z-shaped movement instead.

4. Upgrade Chipsets

Since you will spend part of the gem for High-Tech Chipsets after chapter 27, it would make sense to players that they probably need to upgrade most of their normal Chipsets to Unique grade on or before chapter 27.
The game design in that way, probably.
