The website with the link and the website we're redirected to don't inspire any confidence in me. It looks like a scam and advertising.
In any case, if a beta version that you can actually play does leak online, it should appear on Pirate Bay, Ex.ua, or Rutracker soon.
Let's wait and see. But I'm sure it's a hoax.
Regarding the hysterical adherence to the letter of the law...
For me, this looks strange, to say the least, especially in this case. In my country, my rights are violated every day, and my own state robs me every day. This fact has long removed any moral complexes I might have had about breaking the law (with the exception of the criminal code - the code must be respected! (c) Ostap Bender).
That is, if pirates do their job well, and anti-piracy organizations do theirs poorly, that's not my problem. I personally don't steal, rob, or hack anything. If something suddenly becomes freely available and can be obtained without paying for it, then it would be logical to take it! If there's an opportunity to get something for free, why not?
By the way, many will agree with me after they receive their first paycheck. I'm sure you'll think twice about what to spend the money you earned yourself, and not your parents.
In this case, the situation is ridiculous.
A beta version of a game is not a final product. It's a test launch of the game to find bugs, glitches, balance issues, etc. Why should I pay for this??? That is, we pay to help developers create a final product, which we will then have to buy from them!
By the way, I have a licensed copy of Heroes of Might and Magic V and its expansions, so you can't complain about me.
