Portal developer commentary: Difference between revisions

The '''developer commentary mode''' is a game mode where the commentaries can be found as floating speech bubbles in several rooms of the [[Aperture Science]] Enrichment Center. After finishing the game, the developer commentary mode gets unlocked in the main menu. The commentaries are activated by pressing the [[Controls#Actions|Use Item]] action key on them, and can be stopped in the same way (note that some commentaries can alter the visuals or temporary control of the test subject while they are playing). Take notice that the test subject can't get any achievement while testing in developer commentary mode.
