Bridge Constructor Portal takes Aperture Science lab testing to all new challenging levels. The package also includes the original Bridge Constructor and Bridge Constructor Stunts. Bridge Constructor Portal approaches the world of Aperture Science testing from a completely original angle, bringing the player in as a new employee tasked with building bridges, ramps, slides and other constructions to get the Bendies safely across the finish line in their vehicles. To solve the 60 test chambers, players must make use of gadgets including portals, propulsion gel, and aerial faith plates to bypass dangers such as sentry turrets, acid pools and laser barriers – all under the watchful eye and scathing wit of GLaDOS.
