Swarm Bunker Lust Defense Heroine Roster & Bond Routes

Swarm Bunker Lust Defense is a single-player pixel tower defense with visual novel beats. You hold a fixed bunker with firearms and turrets while Celine, Lina, and Nora rotate through duty shifts, story scenes, and bond progression. Combat strength and adult content both flow from the same bond meter—ignore either side and you will underpower your emplacements or miss story payoffs.

This hub links every character page on the wiki. Use it to pick a main route, plan secondary bonds, and align heroine unlocks with your Weapons tier list and Turrets tier list investments.

The three heroines at a glance

Character	Combat specialty	Best weapon synergy	Route tone
Celine	Rate of fire, MG overheating	Machine guns, auto-gun turrets	Steady, tactical partner
Lina	Explosions, reload speed	Rockets, artillery, rocket turrets	Bold, high-risk bursts
Nora	Spread, close defense	Shotguns, flame turrets	Frontline, breach control

All three appear in the base campaign released August 3, 2026 on Steam (app 4403260). There is no multiplayer roster—bond choices affect solo loadouts only.

Where to start

New players should finish the tutorial bunker, then read How to Play before committing to a route. If you already know TD basics, jump to Bond system for the meter rules that gate combat skills and scenes.

Recommended first route: Celine for forgiving MG sustain, or Nora if you prefer shotgun funnel stages in Act I. Lina rewards players who already understand AoE timing from Turrets guide.

Bond progression overview

Bond levels rise through:

1. Story beats after successful defense nights
2. Optional dialogue in the bunker hub between waves
3. Scene unlocks documented on Unlock scenes
4. Combat nodes that apply passives to weapons and turrets

Missing a defense night can delay a scene but rarely hard-locks a route—check Walkthrough for minimum wave requirements per chapter.

Character pages on this hub

• Celine — MG specialist; best for first-time bunker defenders.
• Lina — Explosive expert; pairs with rocket and artillery metas.
• Nora — Breach control; elevates shotguns and flame emplacements.
• Bond system — Shared rules, meters, combat vs scene unlocks.

Linking characters to your build

Heroine bonds are not cosmetic. A mid-tier MG with Celine’s rate boost can outperform a naked HMG. Before buying another turret on the upgrade checklist, confirm your active route’s next combat node.

Adult content and combat balance

001Studio-NSFW tags the game mature on Steam. Scene unlocks track bond tiers; skipping dialogue still allows combat nodes if you meet wave thresholds. The wiki separates combat advice from scene routing so you can optimize either goal. See Wiki review for content warnings and Steam filter notes.

Tracking progress

Use the stage tracker to note which heroine was on duty during failed waves—bond buffs only apply when that character is active in the bunker shift rotation explained in Bond system.

Updates and new routes

Post-launch patches may add bond nodes or balance heroine passives. Watch Updates after every download; tier shifts often follow heroine skill tweaks more than raw weapon numbers.
