Portal is a first-person puzzle game. Players must solve physical challenges by opening portals to maneuver objects, and themselves, through the enigmatic Aperture Science Laboratories.
These are sounds from Microsoft's Windows Longhorn (which is an unreleased version of Windows with a lovely sound scheme). I do now own these sounds. The fizzling sound is from Portal Project Alpha (which I would HIGHLY recommend you check out if you haven't already), and the Beta turret 'Searching' is from VALVe. The rest are from Longhorn. BTW, these sounds are really quiet, but you can hear them. If anyone knows how to make them louder let me know. You CAN use these in your own mod, but I get to playtest it! :P
