In the 2017 edition of the Halloween event on Overwatch has been added a second mode the "Infinite Revenge", in which the waves will become more and more difficult as we survive by increasing also the number of equal bosses that will appear during the clash, what's worse than a Roadhog? 4 Roadhog or even 5!
In this mode in addition to the usual Ana, McCree, Hanzo and Soldato76 you can select Genji, Torbjorn, Zenyatta and Widowmaker.
As a formation we recommend Private76, McCree, Zenyatta and Torbjorn positioned as follows.

The Swedish engineer will protect the door thanks to his turret that will take care of the Zomnic and Junkenstein's Rotobomb. The bosses, if brought near the turret, will try to destroy it, so use your Ultra to make it more resistant. The turret won't do all the work! Help Private with those Zomnic!
Zenyatta will take Ana's place in this battle by healing the allies and throwing the Globe of Discord at the bosses.
Private 76 and McCree
They will have the same tasks as the first guide with the difference of having to be more mobile.

The bosses' priority, when everyone's there, is always the same:
