Not yet. The first preview build contained just the renders (but there were not implemented in the game yet) and the Halloween 2024 event (and some minor changes, additions such the renders when you start the game etc..)
Second preview build will include the whole last fight and I will have 250+ renders compared to the first preview build. Which mean we are close to 3000+ new renders in total
Second preview build should be released this week-end or early next week
The first preview build will be available here at that moment
