Ok so I may as well give a bit of an update on the start of development. As it appears we are getting closer to the release of Portal 2 Community Edition, I want to give a notice about the usage of the new engine in this mod. We will be using p2ce engine as the core since hammer hasn't aged too well and the version of source Portal 2 runs simply isn't optimized for newer pcs. I also will be switching due to the fact that it is far more flexible and will give me the ability to alter what I need.
