Sorry to disappoint. :(
I sympathize - there are lots of game devblogs I check weekly and it is disheartening when there is a long quiet period, not to mention the Unturned II quiet period has been *very* long.
To avoid unduly raising anyone's hopes I have been trying to be better about "show don't tell" and "actions speak louder than words". I do not want to waste anyone's time. The next time there is news about Unturned II it should ideally be "here is a fun beta worth playing" and iterate upon that, rather than "the boring beta has a physically correct day/night cycle".
