I've been working on the Airex levels lately (as well as City factories, as part of preparing for the long awaited demo release), tweaking the lighting and working on various model replacements for obsolete brush details (like handrails, ventilation pieces, etc.). As much as I dislike teasing people with just that much of information, I'd like to point out that this isn't a 'big' update and I just post this to keep the section a bit more fresh. Be ready for more stuff to come!
