Reports from players on the subreddit and on YouTube suggest that was definitely the case in the beta. Those concepts are still intact in the new game, but the rate at which you normally receive upgrades and upgrade materials could be skewed toward getting you to pay up. All player progress will be wiped at the end of the Closed Beta, and any purchases will be converted to equivalent in-game credits and available in Diablo Immortal at launch.All of Diablo Immortal's microtransactions (expertly explained here) touch on the aspects of the series that used to be all about how you use your time and the risk/reward of attempting higher level dungeons.
In Closed Beta, we will be enabling optional in-game purchases to gain valuable feedback from our community and test the functionality.
In the coming weeks we will also open servers in Korea, Japan, and China, where the game test build will be available in local languages. Starting at 5pm Pacific Time today, Closed Beta servers will be open in Canada, where local players are able to test Diablo Immortal for the very first time, and in Australia. Those lucky adventurers who are invited to the Beta will receive a notification from Google Play soon with details on how they can login and jump into the action. As with previous Diablo Immortal public tests, Closed Beta will only be available on Android and in select regions where a limited number of players will be able to participate.
