A while ago, we uploaded a package of files from 2012 that were originally intended to be released as a 1.0.5 update. We knew the work wasn't really completed, but we had been asked to upload them for others to work with. Since then, a fair few people appear to have downloaded the files hoping to find a proper update for the mod, only to find bugs and confusion. To address this, we've now removed the files again.
But! Worry not. The people who wanted to pick up the torch have acquired the files they needed and are now working on finishing up patch 1.0.5 in a way that will do justice to The Nameless Mod. The new team includes ZeroPresence, who was responsible for almost all the best levels in TNM (such as WorldCorp HQ and ABI HQ) and a couple of people who have worked on Deus Ex Revision.
If you want to follow their progress, you may want to keep an eye on the official TNM Facebook page or joining the discussion on the OTP Discord channel. Or if you're feeling old-school, there is always the TNM Discussion forum on the venerable OTP board. From those of us who no longer have the time to keep working on TNM, we wish them good luck!
