NIKKE Campaign Guide: Chapters, Recommended Power & Outpost Defense

Campaign is organized into Chapters, each containing several Stages leading up to a boss fight at the chapter's end. Every stage clearly shows its Recommended Power — the Combat Power benchmark you should hit before attempting it. Entering a stage while your squad's power is BELOW that benchmark applies a stat PENALTY across the whole squad; the penalty scales with the gap — the further under, the harsher the penalty.

Once a chapter is completed, that chapter's Hard Mode unlocks — noticeably tougher stages in exchange for meaningfully better rewards.

Campaign alternates between 3 mechanically distinct stage types:

• Destroy — defeat all enemy waves plus the main target before the timer runs out.
• Defense — stop enemies from crossing your defense line. The line starts at 20 points; each enemy that gets through costs points by type: normal enemies cost 1, elites cost 3, bosses cost 5. Hitting 0 is a loss.
• Base — hold the occupation score, with both sides starting at 50-50; whichever side reaches 100 points first, or is ahead when time runs out, wins the stage.

The Outpost unlocks after clearing Stage 2-12. Every 5 Campaign stages cleared raises Outpost Defense Level by one tier — a higher level means more self-generated resources and more variety/better quality bonus rewards.

Important detail: Story Mode (a fast story-viewing mode that strips out non-main-path and non-boss battles, and heavily reduces the remaining stages' Combat Power) gives NO Lost Relics, and stages cleared through Story Mode do NOT count toward Outpost Defense Level. Only clearing stages OUTSIDE Story Mode contributes to it.

Some Campaign boss fights are EX Stages — auto-battle is disabled, and every Nikke in your squad is TEMPORARILY fixed at level 80 regardless of how much higher their actual level is. This is the game's way of testing genuine manual skill/rotation execution rather than just how well you've built your roster.
