We really didn't. I got no message about this, nor was I informed beforehand.

Well that sucks. I get that the scene needed to come to an end but...
Of all the awesome ways this scene could've ended. This one was kinda anticlimactic.
Foiled by.. a lot of bullets...

I'd say Kami pretended to go down to end the battle. You could have a few Purge agents charge in during the chaos en confusion of everything collapsing so they can steal Kami (I assume there's a tracker in his armor so they know where he is?) and the antidote from Matt. Maybe cripple him in the processes? Or end up trapping everyone in the rubble or something similarly dramatic.
