Bridge Constructor Portal revives Valve’s murderous but lovable GlaDOS

Crossing rivers with suspension bridges or steel rebar is folksy and quaint, but those methods are too old fashioned for Aperture Science. And in the upcoming Bridge Constructor Portal, due out December 20 on Steam and mobile devices, you’ll get the chance to use the space-time-bending tool from Valve’s Portal games to help vehicles go from point A to point B.

Publisher Headup Games and developer ClockStone Software, which are responsible for the popular Bridge Constructor, are working directly with Valve for this followup. In the standard Bridge Constructor, players design structures over obstacles that must withstand cars and heavy freight trucks. This physics-based puzzler requires you to use your resources strategically to get vehicles safely across without going over your budget. Those mechanics have found a sizable audience, as Bridge Constructor has surpassed more than a million copies sold.
