Defense blocks are mainly simple walls that do nothing. However, they often sport high amounts of health, and can be used to protect your turrets and core from attacks. There are currently 11 types of defensive blocks in the game. Note that on the Android version, the cost and health of most defensive blocks are reduced from those in the PC version, often by roughly 3 or 4 times. The exact cost and health of each block is listed below.
