shot first" scene whereby Han and Greedo realize their first shot didn't do the job so take a second, and then a third, and getting frustrated both start mass repeat firing.
Smoke eventually obscures our view, and after several seconds the firing stops. The dust clears, and we see an exhausted & wobbly Han and Greedo barely standing among the ruins of a completely demolished cantina.
Realizing their guns are too hot to both hold & function, they toss them aside, and catch a breath. Then Greedo points to Han and says, "You shot first!". Han replies, "No I didn't, you did!", They then start a shouting match as the camera backs away from the flattened cantina to reveal the desert with nothing but their echoing arguments.
