Ghost Guardian

The Ghost Guardian is particularly hard to deal with due to the fact it is unable to be hit as it moves through the walls.

These guardians slowly drift about, charging within proximity much like the Snowbot.

Ghost Guardians should be taken out as soon as possible, letting you fight the other guardians from corners with safety.

The Ghost Guardian does not fire. It creates an explosion upon death that can destroy walls but does no damage to the player.
