Greetings friend. I'm Cave Johnson, CEO of Aperture Science. You might know us as a vital participant of the 1968 senate hearing on missing astronauts, and you've most likely used one of the many products we invented but other people have somehow managed to steal from us. Black Mesa can eat my bankrupt... But anyway, here at Aperture Science we have decided to launch a new testing initiative! Says here the lab boys want to examine the effects of moon rocks on brain-dead internet victims like you. But more on that later. To begin the testing, my assistant here ralal (who you may have noticed is transmitting this message) will be updating this post weekly with a new challenge. Pass the test, and you may be up for some in-game rewards! So who wants to earn 20z? The testing area is just up ahead. The quicker you get through, the quicker you'll get your 20 bucks. Caroline, are the compensation vouchers ready?
