Overwatch 2

I'll add some information in regards to this since I was part of this team and general tips.

For Zen something you can do very easily every time is when reaper starts spawning charge your orbs so when he teleports to mid you can easily and quickly land some headshots and do a lot of dmg making him use his wraith right away or brigitte or mcree can stunt for more dps if you have no tires to worry aboot. This a more general tip that applies to every junkenstein mode, and anybody can aim for reapers head during that small gap so you can bolth do a lot of dmg and gain a decent amount of ult from the headshots.

Now on to Brigitte since that who I was during this run. My advice is that your ult is not needed too much since you have a zen ready so save it for when your luring and your low on health. You'll be able to hold your own agains any of the bosses by themselves if you lure them away. Reaper literally can't do enough dmg through your passive healing, Sym can eventually deal enough dmg to kill you so thats when you use your ult, and Roadhog can eventually kill you if he uses his ult but you should hopefully be able to kill him b4hand and the final encounter you can die easily if Junkrat targets you as well as the Roadhog so make sure to use it when you're low. Don't forget your stun ability for Sym to stop her from gaining increase dmg and roadhog to stop his healing and his ult if you can land it. The biggest thing when you successfully lure is to call out the boss health so the others are prepared for the tires to spawn and if need be torb to use his ult near the door for added security. In regards to luring the bosses it seems somewhat random who they'll focus on but I've had the most success when I go right to where they spawn and just swing away even b4 they officially spawn in and try to lure them to the left in the water since this give you at least 2 swings sometimes 3 on the boss tires b4 they get close to the door and it only takes 3 swings to destroy them with Brigitte. I'm sure there is logic to who they target like whose probly doing the most dmg to it, but if your teammates are doing more dmg you could try having them focus on zombradiers and their tires to clear the area b4 unloading on the bosses so you get their attention first. Obviously the benefit of luring the bosses away is to give ample time and room to kill the 2 tires that spawn but the second benefit is that if you can succefully lure the bosses away especially in the final encounter, no one will pay attention to Mcree as he's using high noon and he can 1 shot Mercy and Junkrat with ease plus do a ton of dmg to Roadhog.

Just did it with the team of Torb, Zen, Hanzo and Tracer. Hanzo and Tracer basically stood in for McCree and Brig, respectively.

Was with randoms and no voice chat, so just keep at it if struggling!
