They promised that when the game will be out on steam, there will be a free version, and a paid version, and they will be the same, so if you want to donate to them you will buy the paid version.
I waited for Black Mesa to come out on steam more than 2-3 years, I was really hyped for the Xen levels and the multiplayer and I thought I could play the game and enjoy it on release.
But guess what? No, I cannot enjoy the game. I opened steam and saw that Black Mesa is early access and costs 20 bucks. 20 bucks. 20 BUCKS FOR AN EARLY ACCESS GAME.
20 Bucks is not cheap here, you pay your water bill here with 30. Besides that, Early Access old school shooters dont survive for long (See a game called TOXIKK, a horrible UT3 knockoff and even its developers said that it is a knockoff of UT, its Early Access and after a month of its release it was already dead.) Anyway, after all of the development they still didnt finish the Xen levels which is pretty sad.
Avoid buying Black Mesa, because the developers are liars and make false promises.
Not that I can buy it anyway for that price lol.
