Characters can use these portals to move between rooms or to "fling" objects or themselves across a distance. The Portal is an exploration into discovery, including conversations with thought leaders.

GLaDOS / Turrets / Curiosity Core / Intelligence Core / Self - Commentary Project manager Erik Johnson said Valve's goal for Valve aimed to teach new players the portal mechanics while still entertaining experienced players.The middle section of the single-player campaign takes place in large spaces where few portals can be placed, forcing players to find creative ways to cross.The Repulsion (jumping) and Propulsion (running) gels in The cooperative mode originated from players' requests and from anecdotes of players working together on the same computer or console to solve the game's puzzles.

The player takes the role of Chell in the single-player campaign, as one of two robots—Atlas and P-Body—in the cooperative campaign, or as a simplistic humanoid icon in community-developed puzzles. The initial tutorial levels guide the player through the general movement controls and illustrate how to interact with the environment. Wheatley, driven mad with power, attaches GLaDOS's personality core to a Chell retrieves the potato battery and they form a reluctant partnership to stop Wheatley before his incompetence destroys the facility. According to Wolpaw, the mode was similar to the video game The developers initially envisioned a prequel set in the 1950s, long before GLaDOS took over the Aperture Science facility, with events set in motion when Aperture CEO Cave Johnson is put into a computer, only to realize it was a mistake.The writers originally conceived several premature joke game endings if the player performed certain actions, but these required too much development effort for little payback and were scrapped. Wolpaw likened this to players working together on the same computer to solve Each puzzle chamber in the cooperative mode requires actions from both players. Ascending through laboratories built in the 1960s, 70s and 80s, they discover audio recordings by Aperture Science founder Chell and GLaDOS return to higher levels and navigate Wheatley's distorted test chambers, where they discover the facility is on the verge of collapse.The cooperative story takes place after the single-player campaign, but players are not required to play them in order.The robots are reactivated by GLaDOS one week after the original co-op campaign, during which GLaDOS has already wiped out all of the found test subjects after attempting to turn them into "killing machines".

Young wrote that in the second act, the game "cranks up the difficulty level at a speed that may dishearten casual gamers", and said that particularly when traveling between chambers, he had "absolutely no idea where I was supposed to head next".On April 20, 2011, it was reported that customers had launched a protest against perceived shortcomings of In addition to player-created levels, there have been complete As soon as a playtester discovered a way to complete a puzzle with one set of portals, the level was sent back to the designers for further work.Valve considered a competitive mode.

They sabotage Aperture's manufacturing plants, then confront GLaDOS and perform a core exchange; replacing her with Wheatley as the laboratory's controller. The player must solve puzzles using the 'portal gun' or 'Aperture Science Handheld Portal Device', which can create two portals connecting two distant surfaces depicted as matte white, continuous, and flat. Instead of having them smashed, GLaDOS has the eggs taken to her chamber so that she can raise the baby birds to be her own little killing machines. One of these joke endings was triggered by shooting a portal onto the moon's surface, after which the player's character would die from asphyxiation over a closing song, but the idea of creating a portal on the moon was incorporated into the game's final ending.The writers saw Aperture Science itself as a character. The robots manage to shoo away the bird, earning a rare compliment from GLaDOS before she notices eggs in its nest. The saboteur is revealed to be a bird pecking at the console's keyboard, which sends GLaDOS into a panic when she recognizes it as the one who tried to eat her during her time as a potato battery.
