This long-lost piece of IF from the power duo that brought you such classics as Oo-Topos and Infidel are back in this zany adventure game that is centered around physics principles.As a hapless student zapped into the virtual reality world in your mad professor's machine, you must explore the world where almost everything is a metaphor of principles in particle physics in order to achieve the ultimate goal: be the first human being to see the mysterious particle X. This is a difficult game that has some devious puzzles, although they are all logical. Well-scripted NPCs enhance the atmosphere and overall zaniness.

In 1998, Mike Berlyn has released a much-improved version of this game through his company, Cascade Mountain Publishing, along with Infocom-style feelies scanned in .pdf format. Unfortunately, his company went under in early 2000, and Mike has graciously decided to distribute this new version free of charge. The download here therefore includes both the new remake (plus feelies in .pdf format), as well as the earlier 1987 release. Compare the changes for fun :)
