Bridge Constructor Portal

In the Aperture Science Enrichment Center, you construct bridges, ramps, slides, and other structures to guide the Bendies and their vehicles safely through 60 test chambers. Each chamber turns structural planning into a physics puzzle: designs must support traffic, span obstacles, and carry vehicles to the finish line, either individually or in a convoy.

Portal equipment expands the construction challenges beyond ordinary bridge building. You can place portals, use propulsion and repulsion gel, launch vehicles with aerial faith plates, and manipulate cubes to bypass sentry turrets, acid pools, laser barriers, and other hazards. Switch puzzles, emancipation grills, and complicated routes require careful use of both the structures and the available lab devices. GLaDOS, voiced by Ellen McLain, guides the tutorial and introduces the techniques needed for later tests, giving the chambers a connected progression from basic construction to more demanding physics setups.
