Though the information's a little lacking in detail at the moment, Bridge Constructor Portal takes on the laws of structural engineering and mixes it with some delicious Portal goodness.
You'll roll through test chambers, all the while overlooked by GLaDOS, while you figure out how to get your Aperture trucks across each hazard. Though you'll have the usual bridge construction lark to deal with, you've also got classic Portal mechanics to take into account too.
Players are already responding to the news online and the response... isn't too great judging by the trailer's comments on YouTube. Most of them are receiving the news along the lines of 'I hope this is a joke' and 'Where's Portal 3?'
The game arrives on Mac, PC, Linux, iOS, and Android on December 20th, while the console release, including Nintendo Switch, will be available in 2018.
