Real Escape Game Online: Escape from the Alien Research Facility

If you've played SCRAP's previous live games before and found them a bit wanting, throw away most of those preconceived notions.  This one is more than just audio -- it uses a combination of canned video and live video in sections, and you only need a little bit of suspension of disbelief to make the immersion work.  The puzzles (at least, with the time constraint) are also significantly more challenging, so don't feel too bad if you end up not getting the best ending.
