Swarm Bunker Lust Defense Lina — Demolitions Expert

Lina treats every swarm like a demolition puzzle. Her bond tree in Swarm Bunker Lust Defense amplifies rocket launchers, artillery strikes, and rocket turrets—anything with a fuse and splash radius. Players who already understand AoE timing from How to Play and Turrets guide get the most from her route; beginners may struggle until Act II when scrap flows faster.

Bunker role

On Lina’s shifts she mans explosive weapons first, gaining reload shortcuts and larger blast zones. Visual novel scenes lean playful and reckless—bond rises when you take calculated risks (timed RL shots during elite windows) rather than passive turret-only clears.

Shared meter rules live on Bond system. Combat nodes and adult scenes both require bond tiers; you cannot rush scenes without clearing defense nights.

Combat bond nodes (priority order)

1. Quick Loader — Cuts RL reload; mandatory for rocket S-tier in Weapons tier list.
2. Wide Blast — Increases explosion radius on RL and grenade tools.
3. Shell Sync — Extends splash to artillery and rocket turrets; core pairing with Turrets tier list.
4. Chain Detonation — Secondary explosions on armored kills; Act III power spike.
5. Overpressure — Active skill: next shot double splash with recoil penalty.

Skip Wide Blast only if you rush artillery before personal RL—unusual but viable on Best Build speedruns.

Recommended loadout with Lina

Slot	Recommendation	Notes
Primary	Rocket launcher	HMG secondary for cleanup
Secondary	MG or sidearm	During RL reload windows
Turret 1	Auto-gun	Sustained trash clear
Turret 2	Rocket turret OR artillery	Match chapter armor tables

Track ammo spend on stage tracker—Lina metas burn scrap on explosives if you spam reload nodes too early.

Scene route overview

Lina’s route rewards bold dialogue choices and high-risk wave modifiers (optional elite toggles in Act II hub). Missing optional fights slows bond but does not block core scenes.

Scene tips:

• Accept her side bets in the hub minigame after three successful RL multi-kills.
• Act III branch requires bond tier 5 and cleared artillery tutorial stage.
• See Unlock scenes for CG list and Steam achievement overlap.

Strengths and weaknesses

Strengths: Best anti-armor burst; rocket turret synergy; boss add deletion; scales hard in late Act III.

Weaknesses: Ammo hungry; weak on pure swarm density without auto-gun support; higher skill floor than Celine; friendly-fire risk if artillery angles are wrong.

When to pick Lina over other heroines

Choose Lina if:

• Your failing waves are armored elites, not trash leaks
• You already own RL + one rocket or artillery emplacement
• You enjoy manual burst timing on Steam Deck with gyro aim

Avoid maining Lina if Act I still teaches basic MG mechanics—borrow her shift occasionally instead.

Synergy with other routes

Secondary bond with Celine is popular: Celine sustains, Lina bursts. You still assign one active shift heroine per night—plan rotation in Walkthrough. Nora complements Lina on funnel maps where flame turrets handle trash while Lina deletes elites at the choke.

Investment checklist

1. Unlock RL blueprint (Act I shop)
2. Quick Loader node
3. First rocket turret OR artillery (whichever chapter guide recommends)
4. Wide Blast + Shell Sync
5. RL tier-two mod before luxury sidearm

Matches upgrade checklist explosives branch.

Patch and meta notes

Explosion radius changes hit Lina first. After each Updates entry mentioning rockets or artillery, rerun one armored chapter before respecing turrets. Wiki review collects player tests when patch notes are vague.
