Bridge Constructor Portal [Unlocked]

Welcome to our Science Center Bridge Constructor Portal, a unique fusion of classic Portal and Bridge Constructor games. As a new employee at the Aperture Science test lab, it's your job to build bridges, ramps, slides, and other structures in 60 test chambers and safely haul cargo across the finish line with your vehicles. Use many portable gadgets such as portals, gels, cubes and more to bypass clock towers, acid pools and laser barriers, solve switch puzzles and get them through the test chambers unscathed.
