Nothing to do with Half Life besides someone there being a fan:
As many of you correctly assessed, we’re actually a real company in the Boston area. We’re working hard to assure and secure vaccine and other biological manufacturing production. As much as we would be honored to be part of any Valve game - we do not work in this sector at all. We are not secretly working on Half Life 3, Project White Sands (whatever that is/may be) or any other Valve title - we’re just nerds working to secure the global bioeconomy.
The only reason AW2 happened at all is because Epic paid for its development. Hate on the Epic store all you want (it deserves a lot of it), but it’s one of the few instances where it actually makes perfect sense that it’s an exclusive.
