Sandbox Mode – A Complete Freedom Experience for Strategy Lovers

What Is Sandbox Mode?

Sandbox Mode is a testing environment designed for players who want full control over game mechanics. It allows users to simulate battles without normal game restrictions. This feature is not intended for beginners, as its tools may reveal content or interactions best experienced in normal gameplay first.

How to Access Sandbox Mode

Sandbox Mode becomes available through Seeds, meaning all players can unlock it regardless of rank or progression.

Sandbox Tools and Testing Features

Once inside Sandbox Mode, players gain access to a set of Administrator-style tools, including:

1. Unit Switching

You can replace or swap units during gameplay without restarting the match. This helps players:

  • Test multiple builds
  • Compare tower damage
  • Analyze synergy and placement efficiency

2. Infinite Testing Cash

Unlimited in-game currency allows you to freely upgrade units, test combinations, and simulate late-game scenarios without grinding.

3. Custom Enemy Spawns

Players can spawn any enemy type instantly, at any wave level. This is especially useful for studying:

  • Boss mechanics
  • Wave pacing
  • Damage thresholds
  • Crowd-control limitations

4. Custom Wave Configuration

Adjust waves however you like—speed, size, difficulty, boss-only, or special enemy types. This is critical for players who want to test specific defense setups.

5. More Tools Coming Soon

Developers confirmed that additional Sandbox features will arrive in future patches, expanding creativity and testing potential.


VIP Game Pass Buff – More Power and Better Storage

VIP players receive a major upgrade with this update, providing extra convenience and power.

1. Increased Unit Storage

Storage expands from 500 → 1,000, allowing VIP players to store more units, test more builds, and switch strategies seamlessly.

2. Corn Unit DPS Buff

Corn Unit receives a direct improvement to its DPS output, making it more viable in mid-game and late-game scenarios.

This update clearly emphasizes added value for VIP buyers, rewarding long-time supporters and encouraging new players to consider upgrading.


New Limited Units – Low Stock and High Demand

Two rare units are introduced in the limited-stock Seeds shop. Once they sell out, they may not return for a long time.

1. Dream Petal – 11,111 Seeds

Dream Petal is a unique unit ideal for hybrid defensive setups. Its utility makes it useful in both Sandbox and Endless Mode.

2. Kaboom Shroom – 14,999 Seeds

A high-impact explosive unit designed for burst damage and clearing tough late-game waves. Its rarity and cost make it one of the most sought-after limited releases.

Both units include exclusive effects and animations, adding more personality and flair to your unit collection.


Endless Mode Improvements

The update fixes a major issue with Endless Mode:

Locked Units Now Refresh Properly

Previously, some players experienced bugs where locked units didn’t refresh during Endless Mode rotations. This issue is now resolved, allowing Endless Mode to function as intended.
