Haunted House Online is a real-time multiplayer horror-style tower defense game, where you have to beat other real players! Or, team up with other players to defend against the ghost!

In this game, you need to build a new turret, which will be your base for defeating ghosts. You need to develop the economy to increase your strength. You can only build on the empty floor in the room.

When you are building, you can only build on the floor that is currently empty. You need to upgrade the tower to protect yourself from ghosts.

If you defeat a ghost, you will win the game.

You can only build one turret at a time.
