Incorporating portal physics into the physics of Bridge Constructor will certainly put this on a few Steam wishlists for purchase on Dec 20th. Valve doesn't seem particularly interested in making games like Portal any more, and series co-creator and head writer Erik Wolpaw left the company earlier this year.
We welcome all lucky applicants to Bridge Constructor Portal with our new vehicle-based test chambers, Quantum Tunnels and patented Aperture technology!
Portal has gone all over the place, from the darkest depths of Aperture Science to outer space, briefly. You can see it for yourself in the announcement trailer below.
Due two weeks from today, December 20, Bridge Constructor Portal combines Headup's lighthearted engineering sim with Valve's masterpiece, as it "blends the laws of structural engineering and technology straight from Aperture Laboratories into an exciting new game experience, all under the demanding gaze of GLaDOS". Those mechanics have found a sizable audience, as Bridge Constructor has surpassed more than a million copies sold.
Backing up a bit, if you've never played a Portal game before, I implore you to fix that problem.
Portal 3 might not be a reality anytime soon, but that hasn't stopped Valve from allowing other developers to use its license. In it, players construct spans and supports to allow traffic to flow from one part of the level to another.
Bridge Constructor originally released on PC in 2012 before coming to mobile devices and consoles.
