This is it. I finally upload something. Extract folders, run game and type "map ia_part1" in console.
This is an unusual mod, with the brand new mechanic. The most part of game you will not be able to touch anything: you'll have to interact with boxes, energy balls, doors etc. using portals only.
One person who was supposed to make a few models for me, failed me. Therefore, the full release deferred for some time. However, as I promised to finish it until the end of spring ... I decided to upload the first two chapters of my mod. This is not the final version, so there might be some flaws and bugs. If you find something like this - please tell me in comments.
Demo release will be in the next few days.
And now - some screens of development process.
