The Golden Commando is a single target tower which uses a golden handheld minigun. Originally released as an April Fools joke in the towers section of the in-game lobby.
The Void is the final boss encountered on Wave 40. It is one of the slowest zombies in the game. To make up for this, Void has an extremely high health of 500,000 HP. It has three offensive abilities to aid it in its quest to defeat the towers.
