I have had many situations where I will attempt to sacrifice myself (mostly as a terrorist in a game) to help the team.

Example - Charging at a grp of enemy AI that has taken out several of my teammates. I charge at them I fire the RPG and then they shoot me. Now, in reality, that rpg should have continued to fly at those enemies but in this game, the RPG disappears midflight after I die, why is that?
