"Welcome to the Aperture Science Enrichment Center. Let's look at some of the challenges you will face as a test participant. You may be required to perform simple tasks such as locating an exit. These simple tasks may be supplemented with insurmountable obstacles. Thanks to the Aperture Science Handheld Portal Device, the impossible, is easy." I'm currently on Level 37 of 40. http://armorgames.com/play/107/portal-the-flash-version Oh and remember kiddies..."The cake is a lie. The cake is a lie. The cake is a lie. The cake is a lie." HAVE FUN!
This is very old. It came out BEFORE The Orange Box. That said, it is great and everybody should play it, whether they've played Portal or not.
This is true, however..... This is also true, hopefully some more people get a chance to check it out. It kept me busy while waiting to get the Orange Box for Christmas.
