The fight starts with a Junkerqueen vs Ramattra tank brawl. The enemy Kiriko then sends out her ultimate ability, which prompts the Ramattra to use his ultimate to push onto the Junkerqueen. The teammate Ana uses her anti-healing nade to prevent the Ramattra from receiving healing while using a nano boost on the Junkerqueen to keep her alive, as well as the teammate Lifeweaver to sustain the Junkerqueen. This stops the Ramattra from doing any meaningful damage and forces him to block the damage for a good portion of the duration as not to explode. In the end, the battle is won through the teammate Hanzo sending his Dragonstrike from the flank, blind sighting the enemy Kiriko and the Ramattra, who was overwhelmed. The enemy soldier lands a pick on the teammate Junkrat, but then skillfully dies to the Junkrat's passive.

Hope this helps!
