Cosmic Crisis on Legendary Overwatch 2 

This mode is so difficult that you'd need VERY SKILLED people to play specific characters (because let me tell you right now, Widow's just don't cut it in Legendary). And NEED Extreme level of CAUTION/STRATEGY. Very sad you don't get any reward for completing it on Legendary currently/maybe in the past they had something but not in 2024.
I mean did you see how long this video is?/how many attempts it took to actually complete it? (if you don't wanna watch all the fails just skip to basically the end of the video).
