We do what we can, because, we must.

Hello, fellow scientists. Welcome to the Black Mesa research facility! I look forward to many successful years working together with each of you - pushing our understanding of Science and physics.

You shall all be tasked with the responsibility of operating the facility's new Anti-Mass Spectrometer - we have recently recieved an unusual sample and we think it is the breakthrough in Portal-based technology we have all been searching for. I would like to request all personnel arrive at eight o'clock sharp for a full, and exciting day of Science!

♥♥♥♥ Aperture Science.
