Difficulty: Easy Map Size: Large Map Type: Clean & BTS _ So, I have finished my first map. You start first with normal tests and ... I wont tell more Inn this map are 3 secrets, do you find them all? ^^ Some areas of this map dont look so good, that's because in some areas I had not much experience, but some another areas are looking much better. In Future i will make my maps better, i swear So have fun, and feedback is welcome. (= (Sorry for some lags cough, but the map is completely playable)

While I played in Antichamber I got the good idea... I will do demo map! Alternate Dimension of Illusion (a.k.a. A.D.I. ) is a building which is bigger inside than outside. In this building there is a four-dimensional non-Euclidean space. Alternate Dimension of Illusion on YouTube: http://www.youtube.com/watch?v=thK9lnZJkbA ENJOY!

Note: Some of you might be unable to open the ZIP file. In this case it is advised to download 7-Zip and use that to open the file. The ZIP file uses LZMA compression which isn't supported by all of the archive managers. Four chambers and an easter egg puzzle. Can you solve your way through the Left Wing Facility? Easter Egg Hints: - There is a puzzle element that you have to carry with you to one of the rooms. - Check your spawns. Something might be hidden from the eye there. - A modest award awaits.... I think.. Go for it!

A quick map of an idea I had I made for old times sake. I use antiquated material, but I did not want to break the Portal 1 feel too much. Enjoy!

A small map that requires the player (you) to wait awhile for the Blue Portal to get back around to you. This map was originally made for the mod Blue Portals but I never got around to releasing it. Be sure to check out all my other "Secondary Fire" maps as they get released on the Steam Workshop: http://steamcommunity.com/workshop/file ... d=74481359 NOTE: When the door in the first room is opened pay close attention to the signage on the wall.You may also want to save the game.
