Build Defense is a game that requires creativity and long-term effort, where players must build a fortress from scratch and defend against the creatures of the night. You'll start with a sum of money, but building a solid defense requires more than just the initial amount, as weapons and defensive blocks can be expensive.

This is where Build Defense codes come in handy! Redeem the active codes below to receive freebies and enhance your builds. Be sure to redeem them as soon as possible, as they may expire at any time!
