Step-By-Step Guide

1. Get the Bomb and Go to Next Area
2. Collect 15000 Gear Coins
3. Get Observation Data
4. Submit 15000 Gear Coins

Get the Bomb and Go to Next Area

Get the bomb on the lower left and this will give you the Jackbox Bomb and Tactical Bomb which has a cross-shaped area explosion every 3 steps but does not damage the user.

Destroy the breakable wall on the lower right using the bomb and go to the next area.

Collect 15000 Gear Coins

The next area will have a lot of enemies in the map where you can use your bomb to explode them for Gear Coins. Your goal is to reach 15000 Gear Coins during this section.

Use Overload Charges When Cornered

There may be times where you will be cornered by multiple enemies and be forced to fight. However, you have 4 Overload Charges that you can use to explode your enemies if you are cornered.

If you run out of Overload Charges, you will need to fight the enemy in which you will gain another 4 Overload Charges that you can use.

Use Energy Crystal Conversion

Sometimes, there will be Energy Crystal Conversion monitors appearing in the field. This lets you get bonuses like increased Gear Coin gain, enemies having low chances to take action or converting it to Gear Coins.

Note that getting new bonuses on subsequent conversions will override the previous bonus that you have.

Get Observation Data

Get Observation Data 1 which is located on the lower left of the second map.
