As the video shows, Dosia's Hail Mary grenade that took out two Immortals players in their pivotal grand finals match was one of the flashiest plays of the tournament. Yes, the round was lost, but Dosia's grenade ensured that two IMT players trying to save their equipment in the pit were going to die.
This isn't the first time that Valve has honored a player with in game fame. Marcelo "coldzera" Davis' 4K on Mirage was honored with a sniper rifle with wings spray painted on the walls of the map. Props to Valve for continuing to take time to add lore to their competitive scene.
