Conversion is dead. Outside Influence should still be in development.
I've got my portal mod Portal: Combined Technologies but I've kept it out of the public eye just in case the project gets canceled. If you want there's screenshots of it on my profile, but there is no release date as of yet.
I'm working on a mod for Portal 2 in which you play as one of the surviving employees. It's still very early in development and I'm only finishing the first map as of now. All I can really do are the maps; if I really want this to be a good mod, I'll need help from others of course, for voice acting, modelling, etc. Not sure what I'm naming the mod yet, very bad at names.
Backstock is still slowly churning along
IMO, Conversion was going to be bad, lots of people knew Owlahk (Creator of TWTM) made that super ugly mod TWTM, Conversion just stinked with people who thought they can do anything.
I've started working on a mod. Still unnamed though because I suck at naming things.
