I have an idea for voices of the void. Every 5 days or so you get an email from a scientist saying that they have a unusal object that want dr. Kel to analyze along with other members of the team and they can take you into a new area so that the enviorment feels fresh everytime. That way the environment can feel fresh everytime theres a new object and these objects can clashed ufos, abstact towers, or something scientificly illogical and every time Dr. Kel checks it out there will be puzzles and secrets and bits of the games story that you can find.
