PortalZ Website

PortalZ is my map pack for Portal. Not all levels have been released, but the final version will contain 20 test chambers featuring normal Portal game elements as well as some elements not included in the game, such as Thermal Discouragement Beams and Gravity Manipulation Fields.

Most levels were designed around 2008-2009—before much was known about Portal 2. Thermal Discouragement Beams were added when it was announced Portal 2 would include lasers, but because there was no footage of players interacting with the lasers, the ones in PortalZ behave differently.

You can download the chambers that have been released so far or the demo mappack (the demo only includes half the map pack, and the chambers are lower quality).
