This Portal map-pack contains 3 maps I created that never saw the light of Gamebanana, all created in 2015 after the cancelled development of Psychological Instability.
Untitled (Please insert e-soul) This map is an art project I undertook during my years at Broughton Anglican College. It's blurb is: "The artwork comments on how the future is altering space and enhancing technology, and opens a window for the viewer to comment on whether or not this is a positive or negative reality and what faith they put in the new technologies." You do not use the portal gun in this map. Cleanchamber Originally known as Spawnroom Dev, Cleanchamber was an attempt at replicating the endless opportunities of a Portal mod in a single map file, which contains a spawn room (hence the original name), a waiting room and a simple but well polished chamber. Many of the textures and sound effects are custom, the music being Andrew Huang's "Day by Day". You do not use the portal gun in this map. Funmap A very tiny but oddly creative map that contains the standard Portal textures, both types of cubes and some extra models, all intertwined into an easy to solve but seemingly endless puzzle. It is great for testing mods that affect the default models/materials/sounds.
Extract the contents of the RAR file into Steam\steamapps\common\Portal\portal then open Portal's Bonus Maps section to find the Misc. Jack5 maps collection.
