Bridge Constructor Portal

Build bridges, ramps, and slides inside Aperture Science test chambers, then send forklifts through them without losing the vehicles or their drivers. Structural strength is only half the problem: portals redirect traffic, propulsion gel changes speed, and aerial faith plates turn a safe-looking crossing into a launch trajectory. Position supports and cables around lasers, turrets, and acid, then run tests to see where your design buckles or vehicles collide. Sending a convoy adds pressure that a single successful crossing may not reveal. The base game contains 60 chambers; the separately purchased Portal Proficiency expansion adds 30 more and lets you choose portal positions yourself.
