I recently noticed that when you play as brim with KAYO’s gun buddy it will open up. Are there any other secretes like this within the game among agents? Thanks!

I was just playing on B main, Ascent. Walk in, BOOM! Skye flash. No big deal, keep walking, then BOOM! Another flash. Again, I hide for a second. Then I get flashed by Skye's 3rd flash, the enemy Phoenix's flashes, Reyna's flashes, Breach's...
