Kaiju No. 8: The Game - Expedition Mode Guide

Expedition is a progression mode where your squad advances through distance stages, defeats Kaiju waves, and earns resources over time. It works like a hybrid between idle gameplay and scaling strategy. You can play actively for short pushes, but your long-term value comes from smart resets and passive farming. It's a mini-game featuring characters from the game that lets you earn some resources. You don't have to complete it, but it's pretty fun, so it's worth giving it a try.

Every run starts with your team pushing kilometers automatically. As you move forward, enemy strength rises sharply and your relative damage declines, so progression slows down. The key to success is to farm gold efficiently, invest in upgrades that boost your damage and gold gain, then strategically reset to convert your run progress into permanent growth.

The mode is designed to encourage a cycle of active play, passive farming, and strategic resets. As we unlock new characters and use them in raids, they gain experience, level up, and earn points that we can use to improve their stats, such as strength, HP, speed, attack speed, etc., as well as group bonuses like Tap Damage. It’s important to distribute those points after each raid. We’ll always use all the characters we have; the roster isn’t larger than the current capacity of characters we can have deployed.

• You can tap to deal extra manual damage (auto click recommended).
• Missiles and abilities scale with your total attack.
• Your team continues generating gold passively after you leave the mode (so important).

Strategic Retreat is the core optimization mechanic. Resetting may look like lost progress, but it is how you convert one run into permanent growth. Why? because there is a point in the run where your progress slows down so much that the value of continuing is less than the value of resetting and starting a new run with your improved stats. This is the fundamental loop of Expedition: farm, upgrade, reset, repeat.

• Gain special expedition currency and progression materials.
• Collect loot boxes and reset rewards tied to your reached distance.
• Reinvest upgrades to push farther on the next run.

In practice, resets beat overextended runs once your progress becomes too slow at high distance.

Expedition currency has a weekly cap of 1000 points. This resource is valuable, so spend it on high-impact items first. Here depends in your needs and your current progression, but generally, summon tickets and stamina are the best early purchases for most players. After that, focus on high-tier gear upgrades that boost your damage and survivability in the main game. Avoid spending points on low-impact items or things you can easily get through regular gameplay, as that reduces the overall value you get from your weekly rewards.

After hitting the cap, extra runs still matter for internal growth (gold and upgrades), but not for additional weekly shop currency.

Hard Mode is a more challenging version of Expedition that offers better rewards. The core mechanics are the same, but enemy strength and difficulty are increased, so it requires more careful optimization and stronger stats to progress effectively. Don't panic when the enemies start hitting much harder and are a lot faster. This is expected and is part of the design to encourage resets and optimization.

Many players get very large overnight gains by combining short active pushes with longer idle windows.

Expedition Mode is about optimization, not constant grinding. Prioritize automation early, use idle farming intentionally, reset on time, and invest in gold efficiency. Just remember this is a minigame inside a game, so don't stress about perfection. Focus on learning the loop and enjoying the progression, and the rewards will come naturally over time.
