Phantom Invasion is a members-only den item and a den version of the mini-game Phantom Invasion. It was first released during May 2012 as one of the Monthly Member Gifts, and it was later added to the Diamond Shop in May 2013.
This item is a large, futuristic-styled arcade machine that consists of a wide base with a tall screen in the center and a rounded prize dispenser on one side. The base of the arcade machine has an oval button in the center and a coin slot off to one side. The screen on top of the system displays a UFO with a phantom inside. The prize dispenser portion of the machine has a rounded glass viewing window on the front and an animated display on the top that shows icons for three Phantoms as well as a UFO. This item has only one variety.
- The den version of the game is unique in that it can reward a Phantom Toy that the Sol Arcade version does not have.
