It's set for a Fall release so it should be anytime now !
Shadow Fight 3 Confirmed For A Fall Release - App Trigger
When Shadow Fight 3 Will Release?
Great question. Personally, I can not wait. I adored Shadow Fight 2 and haven't stopped playing it since release. I have heard a lot of great things about it's up-and-coming successer and it has me hyped beyond belief. I can only hope the new graphics they are promising won't make for a laggy experience on my 1942 tablet (not really that old, but it mght as well be). If Nekki live up to their countless promises then this will be a real game changer and set the bar for other games of its genre.
It think it will be released somewhat in October or November.
