Portal is a first-person puzzle game. Players must solve physical challenges by opening portals to maneuver objects, and themselves, through the enigmatic Aperture Science Laboratories.
These are some early Portal 2005 Alpha nova prospekt prefabs, I dont know how to use hammer so if any of you do and can make a map with these prefabs for portal then that would be awesome :), the screenshot is not mine its a screenshot I found because I dont have any screenshot of these prefabs :>
This is good for hammer mapping.
