About Battery Defender

⚡️ Build your defense… one battery at a time!
Welcome to Battery Defender, a unique strategy and automation game where you design a conveyor belt network to deliver energy batteries to your turrets and fend off waves of enemies!

🧠 Plan smart. Build better. Survive longer.
Gameplay is split into two phases:
🔧 Preparation Phase – Place, merge, and optimize your belts and turrets. Design the perfect power grid to fuel your defense.
⚔️ Combat Phase – Enemies attack! Your turrets fire automatically based on your setup. No turning back — your planning is everything.

🔋 Core Mechanics:

A battery generator produces energy over time.

Conveyor belts transport batteries to turrets and power-consuming structures.

Each turret requires a specific energy amount to activate and fire, then enters a short cooldown.

Batteries that reach a full or cooling turret keep moving — no waste allowed!

Merge identical belts and turrets to enhance their power and efficiency.

🛠️ Design your energy network:

Belts in various shapes: straight, long, L-turns, crossings, and more.

Energy multipliers: upgrade belts to duplicate transported batteries (x2, x3…).

Multiple battery levels (⚡1, ⚡2, ⚡5) and upgradable generators.

👾 Survive relentless enemy waves by constantly refining your circuit design and tactical choices. Can your grid handle the pressure?
