This sounds like what I heard back in 2018. It was supposed to be out in April to tie into Endgame, but it seems like tech issues got in the way. There's a lot relying on using your hands as weapons which is far, far more trickier on tracking than guns with RFIDs built in. They already knew last year that this was going to be a "level up" for the experience, that seemed to prove correct. There's also SUPPOSED to be two more experiences in 2019, and I was not told if it was Disney or not. I assumed one of them was Frozen 2, but Damage Control being severely delayed may have pushed these projects into 2020.
I'll be doing the experience later this week, I'll let you guys know how it is.
