This 2007 main game is a first-person puzzle-platformer adventure where you navigate test chambers in the Aperture Science facility using the Handheld Portal Device, which creates linked spatial portals. The core loop involves solving physics-based environmental challenges by strategically placing these portals to manipulate momentum and traverse obstacles. The narrative unfolds through interactions with the facility's AI, GLaDOS, contrasting sterile testing environments with dilapidated hidden areas. It is available on PC, consoles, and mobile platforms.
