What a misleading title...

And it’s on Steam feed. I seriously freaked out for a moment.

Edit: deleted it.

I’m sorry but how is that title from the article misleading? It did says mod, not game.

It’s still a community-made mod, only sold on Steam.

It’s a game. It’s standalone, and uses practically nothing of the game it started as a mod of.

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
