I saw a better version of the clip. And I saw, that the scene in the store, were the two guys are killed by the plasma gun of the predator, is different. When they show the 2 plasma ball flowing to their heads, they are standing in different positions, and they don't have shotguns in their hands. In fact, they are empty handed! And, the nuclear bomb does strike the city! Because when the explosion is shown, we see the plane from witch the bomb landed
