The Pixel Gun Arcade is a Big Decor introduced in the 16.7.0 update.
It appears to be a bluish purplish arcade in which the game is Pixel Gun 3D. There is a banner of the game on the side with the title and Newbie on it. There is also a screen with a joystick and some other controls seen on normal arcade games. The screen indicates the player in the first person equipped with the Pixel Gun, aiming at a zombie.
As of now, it has no use and is just used for cosmetic purposes.
- Pixel Gun 3D never had an arcade game in real life, because the game wasn't out in the 80's. It was out only in 2013.
