i think you're still able to late pledge here for beta access aether-studios.pledgemanager.com/projects/rivals-2/participate/ , but the June beta weekend just ended. I'm not sure if there are more beta weekends to come :(
Just wanted to chime in & say you are still able to pledge for beta access and that there are two more confirmed beta weekends (end of July & end of August). Definitely pledge if you are able, if only to show support great combos btw lol
