The Cactus Wall is a placeable block that is used in the background. It does not block monsters from walking into your home, although it is one of the requirements for an NPC house (any type of wall will do). Along with a light source, it is used to prevent Monsters from spawning. Like all Walls, it can only be broken with a hammer or a hamaxe. It can also be destroyed by using explosives.
- Cactus Walls can be used by newer players to create their starting house, as it is easy to obtain near the beginning of the game.
- Added to the game.
