Reinhardt's ultimate ability allows him to knock down all enemies within a 20-meter cone-shaped vicinity in front of him. The ability deals damage and stuns enemies for 2.5 seconds but can be blocked by barriers. Unfortunately for the enemy team in the clip below, not even a wall could stop the Reinhardt from destroying the entire team.
Overwatch Player 6-Man Shatters Enemy Team
Posted by Reddit user u/Blaximusta, the 27-second clip titled "6-Man shatter with teammate reaction" follows Reinhardt through his ultimate ability, Earthshatter. Before his ability is activated, Reinhardt takes a swipe at the player in front of him. The enemy player got stuck outside the wall and was killed instantly. He then proceeds to get stunned next to the enemy wall for a few seconds before he hammers down the wall while getting healed. Once the wall is down, he leads his team forward and strikes his ultimate down sending a shock wave straight towards the enemy team.
Because the enemy team was unprotected, Reinhardt was able to get a clean six-man wipe. His teammate, who was already fired up from Reinhardt's two-piece, then proceeds to lose it, getting beyond excited that his teammate just did that.
