Main menu
The Main Menu of Portal and Portal 2 are hubs for accessing different game modes, changing in-game options such as sound and graphics settings, and viewing additional content.
Portal
The main menu is the first interactive screen shown after starting up Portal. It provides access to a number of options that the player can use to commence a new game, access bonus maps, or continue from an existing savegame.
There is also an option to begin the game with developer commentary, view a list of achievements, and a access list of options that the player can change, including the control scheme, sound and visual settings.
The player can close the game by selecting "Quit".
Portal 2
The main menu is the first interactive screen shown after starting up Portal 2.
The main menu allows the player to begin a single player campaign, join the Cooperative Testing Initiative campaign, or manage in-game settings. Additional videos and concept art can be accessed by clicking the Extras option, and Robot Enrichment allows the player access to their Cooperative Testing Initiative Backpack.
The Portal 2 menu features several backgrounds that display pre-rendered videos, which correspond to the story chapter currently being undertaken in the single player campaign.
The player can close the game by selecting "Quit".
