Destroyed City Overview & Unlocks
Conquering skibi defense chapter 9, widely known as Destroyed City, is the ultimate test of your strategic planning and execution. Taking place during the intense Astro Arc, this stage pits you against waves of fast, heavily shielded Astro enemies. It currently stands as the most challenging story mode chapter in the game. Success requires precise timing, specific tower configurations, and quick reflexes during wave transitions.
Completing this chapter yields massive progression rewards. Not only do you secure a hefty sum of in-game currency, but you also unlock access to some of the most powerful late-game towers in the current meta.
| Metric | Detail |
|---|---|
| Difficulty | Hardest Story Mode |
| Completion Reward | 20,000 Credits |
| Theme | Destroyed City / Astro Arc |
| Primary Threat | Astro Faction Enemies |
Defeating the final boss unlocks the ability to purchase four essential towers from the shop. These units are critical for tackling endless modes and high-tier challenges.
| Tower | Role | Base Cost |
|---|---|---|
| Commander Camera Girl | Support / Buffs | Medium |
| Chair Phase 1 | Defense / Utility | Low |
| G-Toilet 5.0 | Heavy DPS | High |
| Upgraded Speaker Mech | Balanced Offense | Medium |
Astro enemies move significantly faster than standard units and often possess shields that block initial damage. Do not rely solely on slow-firing, single-target towers.

Recommended Towers & Loadout
To survive the onslaught of the Astro Arc, your loadout must balance early-game cost efficiency, rapid economy generation, and overwhelming late-game area-of-effect damage. You cannot afford to waste placement slots on underperforming units.
Early Defense
- Bladerunner Speakerguy: Fast melee slices to clear early waves.
- Brute Speakerguy: High single-target damage for early mini-bosses.
- Cost Efficient: Minimal investment required before Wave 10.
Economy & Support
- Dancing Camera: Generates the cash flow needed for Titan upgrades.
- Upgraded DJ Girl: Provides essential range and damage buffs.
- Alliance DJ: Deployed at the secondary spawn point to secure the late game.
Late Game DPS
- Upgraded Polycephaly: Clears massive groups with area-of-effect damage.
- Prime Colossal Camera: Melts the final boss with high sustained DPS.
- Upgraded Colossal TV Guy: Alternative high-tier DPS option.
Skins and perks play a major role in optimizing your towers. Equipping your units with Diamond or Cursed skins provides the stat boosts necessary to survive the final waves.
| Tower | Rating | Recommended Skin/Perk |
|---|---|---|
| Upgraded Polycephaly | 5/5 | Konda Perk / Enhanced Armor |
| Dancing Camera | 5/5 | Diamond Skin |
| Prime Colossal Camera | 5/5 | Cursed Skin |
| Alliance DJ | 4/5 | Diamond Skin |
| G-Toilet 4.0 | 4/5 | Default / Speed Build |
Ensure all your primary towers are maxed out in the lobby before launching the chapter. Entering the Destroyed City with unupgraded base stats makes the final waves nearly impossible to defend.
Step-by-Step Strategy & Wave Management
The defining mechanic of skibi defense chapter 9 is the spawn point relocation. At Wave 10, the direction of the enemy attack changes entirely, forcing you to pivot your entire defensive setup.
Establish Early Economy and Defense
Begin by placing Bladerunner Speakerguys and Brute Speakerguys near the first spawn point to handle the initial waves. Simultaneously, place Dancing Cameras in a safe corner and begin upgrading them immediately to build your cash reserves. Use Upgraded DJ Girl to buff your defenders.
Prepare the Secondary Spawn Point
Before Wave 10 begins, place Alliance DJ at the secondary spawn point. Do not upgrade it yet, but ensure it is positioned to cover the path where the new wave of enemies will emerge. Keep farming with your Dancing Cameras.
The Wave 10 Pivot
As soon as Wave 10 starts, the spawn points switch. Immediately sell all defense units at the initial spawn point. Relocate your defensive line to the Alliance DJ. Place Upgraded DJ Girl and Upgraded Polycephaly (equipped with the Konda perk and Enhanced Armor skin) and max them out.
Deploy Titans for the Destructor Boss
Place down the Upgraded DJ Toilet Mech and begin upgrading him. As the final boss, the Destructor, approaches, deploy your Prime Colossal Camera or Upgraded Colossal TV Guy to deliver the final blow. If needed, use G-Toilet 4.0 to speed up the process.
Managing this transition smoothly is the difference between an easy victory and a sudden defeat. Use the table below to track your actions per wave.
| Wave Range | Primary Focus | Key Action |
|---|---|---|
| Waves 1-9 | Economy & Base Defense | Maximize Dancing Cameras; hold the line with Brutes. |
| Wave 10 | Relocation | Sell starting units; place Upgraded Polycephaly at spawn 2. |
| Waves 11-19 | Mid-Game Scaling | Upgrade DJ Toilet Mech; max out support buffs. |
| Wave 20 | Boss Elimination | Deploy Prime Colossal Camera; focus fire on the Destructor. |
Do not hesitate during the Wave 10 transition. If you delay selling your early-game units, you will lack the funds to deploy Upgraded Polycephaly at the second spawn point, leading to an immediate leak.
Preparation Checklist & Final Tips
Before heading into the match, run through this checklist to ensure your account and loadout are fully prepared for the difficulty spike of the Astro Arc.
Pre-Game Checklist:
- Max out all selected tower levels in the main lobby.
- Equip the Konda perk on Upgraded Polycephaly.
- Apply Diamond or Cursed skins to your support and DPS units.
- Familiarize yourself with the hotkeys for selling towers quickly.
- Ensure your loadout contains at least one high-yield economy unit.
Skins provide passive modifiers that stack with your tower perks. Selecting the right combination is key to surviving the high health pools of late-game Astro enemies.
| Skin / Perk | Primary Benefit | Best Target Unit |
|---|---|---|
| Diamond Skin | Boosts range and reduces upgrade costs | Support units & Economy |
| Cursed Skin | Greatly increases raw damage output | Late-game Titans |
| Konda Perk | Increases attack speed | Upgraded Polycephaly |
| Enhanced Armor | Adds defensive shields to the tower | Frontline block units |
Once the Destructor falls, you will immediately receive your 20,000 credits. Head straight to the shop to purchase G-Toilet 5.0 and Commander Camera Girl to bolster your roster for endless mode.

As soon as Wave 10 begins, sell all defensive units at the first spawn point. Immediately move your focus to the second spawn point, utilizing the funds to place and max out Upgraded Polycephaly next to your Alliance DJ.
