All Source games are supported and the company is open to all. Cyberbullying and harassment will not be tolerated and is grounds for immediate termination. Collaboration is optional, but given our current state of being and us all trapped indoors, it is recommended. Plus, our boss is going crazy trying to make a movie and we're understaffed by a long shot, so we need all the help we can get. Finally, for a mod to be published, it has to have at least started development.






And also, it can't be spinoffs of Hunt Down The Freeman.
