Bridge Constructor Portal

Bridge Constructor Portal merges two long-running puzzle franchises into a single Aperture Science Enrichment Center test program. As a new employee at the Aperture lab, your job is to build bridges, ramps, slides, and other constructions across 60 test chambers, and to get the Bendies (the small vehicle-mounted test subjects) safely to the finish line of each.

The Portal toolkit makes the construction strange. Portals teleport vehicles mid-fall. Propulsion gel speeds them up. Repulsion gel bounces them off surfaces. Aerial faith plates launch them. Cubes weigh down switches. Sentry turrets, acid pools, and laser barriers all act as obstacles your structure must route around. Solving a chamber means designing a path that uses the Portal gadgets correctly, in addition to ensuring the physics of the bridge itself hold up under the strain of the run.

Ellen McLain returns to voice GLaDOS, guiding you through the tutorial with the original character's trademark sarcasm. The Level Editor lets you create your own test chambers and share them with the community. The merge of the two franchises is the entire pitch — the bridge is a lie, in the game's own words.
