For what it’s worth, I am sorry to let you down. 
I know you in particular were excited when I mentioned focusing on Unturned II again at the end of May. Some discussion of character designs is definitely not much to show for it.
You are right that I did not feel as passionate working on it in June as I did when the project started. Two of the main things I worked on were base building and some character stuff. I think the reason I did not feel as excited was because I feel optimistic to make similar base building improvements to Unturned (3.0), and there has been a lot of recent discussion about it, so it felt like “what is the purpose of doing this here in Unturned II (4.0) rather than in Unturned (3.0)?” Similarly with the characters I thought the revision might be a great upgrade to fix some of the issues carried over from the original game, but considering the mixed feedback again it felt like the improvement between games was not big enough.
Obviously upgrading the base building in Unturned (3.0) is a lot slower because it means backwards compatibility for mods and plugins, and requires more netcode rewrites (planned as part of 2021), but for these sorts of improvements I feel like if it’s possible in 3 it should be done for 3. i.e. I want 4 to be “the impossible” upgrades like entirely redesigning the character.
In retrospect, a lot of my statements about Unturned II have been irresponsible because it has been delayed so much. IIRC a 2018 contract with Epic says its expected early access release date was late 2018. I am being too much of a perfectionist. I wish I could say when I will be happy enough with the foundation to commit to a consistent update schedule.
