I am a geek!
This the beta version of my Portal map pack, Portal_Z. It contains a mixture of both normal, Portal-ish, test chambers and some creative ones that I call "Source experiments" (the name is based on the name "Chrome experiments"), in which I tried to recreate games like MineSweeper, Labyrinth, Peggle, and Cube Runner in Portal (not all of those are included in the demo, but they will be in the final version) Please try it and tell me what you think! Some of the ideas used in it were inspired by We Create Stuff's Portal: The Flash Version Mappack, created by Hen Mazolski, and Portal: Prelude, created by Nicholas "NykO18" Grevet, Jérémy "Capitaine Mousse" Barbe, and Marc "moroes" Bidoul. I hope you enjoy the map pack!
