The idea of having a Portal 2 that doesn’t involve portals seems incredibly ridiculous. However, according to a PC Gamer interview with some of the team at Valve (via Joystiq), that is the direction the project was headed in originally.  Valve’s Erik Wolpaw posits “What if [the Portal franchise] was always about introducing a new puzzle element that you’re going through?” He continues stating “It’s about Aperture Science, and now you’re going through this new testing track with this new element.” Apparently, the team first tried using paint, which eventually became the gel in Portal 2, and a gravity gun, although the testers all wanted use of the portal gun, leading to its return as the central puzzle mechanic. |
