From what visual perspective is Portal played?

Portal is played from a first-person perspective.

The camera shows the world through the viewpoint of Chell, the player character, rather than displaying her as a visible third-person avatar. Players see the portal gun, carried objects, environmental hazards, and test chambers as if looking through Chell’s eyes. This perspective makes the game’s spatial puzzles especially direct: players must judge distances, angles, surfaces, and portal placement from their own viewpoint.

Portal’s first-person presentation is closely tied to its three-dimensional portal mechanics. A portal connects two locations, and walking or falling through it changes the player’s position while preserving momentum. Because the camera travels through the opening, players can look through one portal and see another area of the chamber before entering it.

The perspective can be confused with a first-person shooter because Portal uses familiar controls and was built on Valve’s Source engine. However, combat is not the game’s central activity. Portal is primarily a puzzle-platform game, and its first-person viewpoint serves exploration, experimentation, and spatial reasoning. The same broad perspective continues in Portal 2, which expands the formula with new gels, surfaces, and cooperative puzzles.
