What is the Expedition?
Idle Content with Strategic Elements

Unlock Conditions | 1. Player Rank: 10 2. Main Story: Clear 1-9 |
The Expedition in Kaiju No. 8 is an idle mode with strategic elements that reward players with Stamina and Credits. It features strong mini-game mechanics, with character Reinforcement being self-contained within the Expedition and separate from the main progression.
Earn Rewards Based on Distance Reached

In the Expedition, rewards increase with the distance your characters travel. Enhance your squad and refine preparations to maximize the rewards earned in each run.
Earn All Rewards by Playing Regularly
The Expedition has a weekly cap of 1,000 Points. Reaching this cap ensures you won't miss any rewards. Character Enhancements mainly improve efficiency by cutting down playtime and required runs.
Tips for the Expedition
- Enhance Characters, Mission, and Command
- Complete it Manually
- Use Commands
- Purchase Characters with Dimensional Crystals
Enhance Characters, Mission, and Leadership
During an Expedition, deployed characters automatically attack and advance. The money needed for enhancements is obtained by defeating enemies or completing missions. Early on, it's recommended to enhance missions first, then invest in character enhancements if they're at risk of being defeated.
Major Enhancements Possible Every 10 Levels
Characters, Missions, and Command can be significantly enhanced every 10 levels, granting a large boost at each level. When Reinforcing, focus on reaching these major enhancements.
Complete Mission Manually
By completing missions manually, you can efficiently earn money and progress your enhancements. While it requires more effort, it yields greater rewards in a single expedition.
You Can Also Automate Mission
Missions can be automated using the Command Rewards earned based on the distance cleared in Expeditions. This removes the need to tap for Missions every few seconds, making it ideal for players who prefer a more relaxed playstyle.
Use Command
Command actions are manual inputs by the player, such as attacking enemy Kaiju or buffing characters. While completing Missions manually takes priority during regular progress, use character Enhancements and attacks primarily during boss battles.
Buy Characters and Buffs with Crystals

Dimensional Crystals can be used to purchase characters or unlock their Reinforcement caps. Although valuable, using them can help you earn Expedition Points more efficiently.
Soshiro Hoshina is Recommended
Costing 400 Dimensional Crystals, Soshiro Hoshina has strong stats and performs well even when idle in the early stages. He greatly smooths progression, making him a top priority if you plan to spend Crystals in the Expedition.
Expedition Rewards
Exchange Neutralization Points for Items

Expedition Points can be exchanged in the shop for items, including limited rewards like "THE GAME Gacha Tickets" and "Stamina Recovery Agents". Aim for the weekly cap of 1,000 points to get them all.
Featured Items | Points Required | Exchange Limit |
THE GAME Gacha Ticket | 100/1 ticket | 5 times |
Stamina Recovery Agent | 50/1 item | 10 times |
Unit Part Materials | 20-40/1 item | 50 times |
Receive Idle Rewards
Stamina can be recovered through idle rewards in the Expedition. The higher your Special Task Rank, the longer the maximum accumulation time, allowing for extended idle periods.
[Recommended] Recover with Quick Collect
You can also recover Stamina using Quick Collect for Neutralization rewards. It's limited to 5 times per day, but even after 5 uses, it's more efficient than spending Dimensional Crystals, so it should be prioritized.
Times | Dimensional Crystals Required |
1st-2nd time | 20 |
3rd-4th time | 30 |
5th time | 50 |
