Portal is free, Aperture couldn’t be happier

Steam for the Mac has been released, and Aperture Science couldn’t be happier and will let you know why Portal will be available for free on steam until May 24, 2010(no strings attached).

Yesterday, millions of new recruits poured into the Aperture Science Enrichment Center for Portal testing. If they are ever found, we are sure they would want you to know that the wheels of science turn ever onward. Today, in an effort to restaff, Aperture Science directs your attention to this motivational recruitment video.
