Defense Platform

"The foundation upon which your base defense is built. Higher level platforms have more armor,which make them tougher to take down."

- In-game description

Introduced in the 19th of October, 2012 Dynamic turrets update.

Tips
If you equip a turret and then upgrade that turret type in the Defense Lab, the existing turrets will NOT level up. You will have to re-equip those turrets.

IE: If you have a level 2 Machine Gun turret and then you upgrade the Machine Gun turrets to level 5 in the Defense Lab, your existing turret stays level 2 until you equip a new Machine Gun turret to that platform.

If you upgrade a defense Platform, the existing turret will stay on the platform during and after the upgrade. Your turret will still take full power during the upgrade.

Upgrading the Defense Platform from level 2 to level 3 gives 3.6 million experience points.
