One of the big things we want to finish before exiting beta is the replacement of the main UI. Honestly, it's a mess, as we've continually added features to it while ignoring that it's harder and harder to understand for new users. We're about at that point where we want to start organizing it, and the first bits of this you can see with a new Friends movable menu and a movable Inventory menu. Both are considered "in progress" but we're excited to bit by bit move everything off of the old UI so we can finally present a clean fresh (final?) UI ahead of exiting Beta.
Another big feature we've wanted is the Map Editor, and we debated internally if we should even show people at this point. But since Prime users get the Map Editor no matter what when it's finished, we might as well let you see it as we're working on it--but yes we know there's a ton of bugs and incomplete things. Expect to see progress on this every patch.
You'll also see a reference to Sandbox Mode if you are Prime, and this feature will probably be coming to VIP players when complete. Instead of a full editor, it will focus on letting you move and duplicate units while you pause the game, then resume it and play from there. We may add more more features to it, with the goal to be a fun thing to mess around with in solo games, while doing full map editing will be reserved for Prime owners.
Feedback from players has led to a new unit being created, the Stinger! We're in the middle of rebalancing the Seeker and having a similar unit that's not mobile gives us some options to create some interesting choices. There's other balance tweaks which have come from the community, see below for full details.
