About This Game

The game
Portal: Lost in Aperture is a mod for Portal 1. There are some new level with a new story. The goal of this mod is not the hard puzzles, instead of the feeling of the Aperture Science. It shows Aperture from a new perspective. Maybe it is not lore accurate, but have a simple story.

The future of the game
I will try to add more level and fix bugs, if it's needed.
