Main menu

Portal 1
The main menu is the first interactive screen shown after starting Portal. It gives the option to start a single player game or manage the game settings.

Portal 2


The main menu is the first interactive screen shown after starting Portal 2. It gives the option to start a single player or cooperative game and manage game settings. There are also extra videos and art shown by clicking the Extras option. Robot Enrichment gives the player access to their co-op backpack. The backgrounds show pre-rendered videos.

One difference between Portal 1 & Portal 2's Main menu screen is that Portal 2's Main menu changes according to what chapter you are on.
