I have decided to move the mod to the Portal 2 engine when it is released. This change will include a change of the non-cyber textures, styling and some gameplay elements to those of Portal 2. As such major changes are going to be made to non-cyber areas, I am going to halt most development of these until after the release of the Portal 2 sdk. I will therefore be switching my main efforts to the cyber areas, which will experience the least change. It also means that the mod will not be released until sometime after the release of Portal 2, although a release date is still to be determined.
Hopefully I will have some new media to present soon.
