Well, it took a while longer than we were expecting, but at last, the BMSC rendition of Forget About Freeman is live on the Steam Workshop! It can be found here. There are one or two small bugs that we know slipped under the radar here, but they're nothing too serious. One is just a clipping problem with some doors, and the other is that the guard in the first map might need some coercion to head up to the sewer entrance - which isn't necessary for gameplay, so it's not too big a deal.
I'm probably going to take a bit of a break before I look into Lambda Core. These last few months have been exhausting for a multitude of reasons, and FAF itself ended up taking a lot more work than anticipated, but I think it paid off quite well.
I'm not going to make a post about it, but I'll be updating the full BMSC workshop addon to include FAF soon too.
