Portal Pinball is paid DLC for Pinball FX2 by Zen studios. It features a pinball "board" styled after a Portal 2 test chamber in disrepair, and includes cameos from several members of the cast of the Portal series including Chell, GLaDOS, Atlas, P-Body, and Wheatley. On mobile, Portal Pinball is available as a standalone title.
It is worth noting that Portal Pinball contains elements from both Portal and Portal 2, including content present in the former but was cut from the latter. An example of this is how Portal's High Energy Pellet launchers and catchers are present, as well as the Thermal Discouragement Beam, which replaced the Pellets in Portal 2. Another example of which is how GLaDOS' model is that of Portal 2's, but attached to her chassis are the television monitors from the first Portal game. The cyan glass maintenance platform from Portal's Central AI Chamber is also included.
All of the character dialogue was ripped from the Portal games' files; No additional voice acting was recorded by Ellen McLain (GLaDOS), [[Stephen Merchant] (Wheatley), or [[Dee Bradley Baker]] (Atlas & P-body).
There is no story-related content in Portal Pinball.
