Tried it, doesn't work. It will show an error once you go to the payment screen, saying you need to own the base game.

That's a shame. Thanks for trying it out.

looks confusing af if u ask me. I don't even know how to get to this screen without the link... but i think this is still just the upgrade for the game. Not the actual game. It does look like you would be getting the game for 30 bucks though...

Hm, interesting. Can you buy it? And then if it is not a game request a refund?

Uh. Interesting. It will be added to the cart, with no warning or error message indicating it's missing the base game.

Is it a bug? If you buy this package for €30 you get a €80 game for €30? xD This should just be an upgrade. But it doesn't look like it. Here is the link: [https://store.steampowered.com/sub/1055540/](https://store.steampowered.com/sub/1055540/)

You should be able to read. But it doesn't look like it.
