void OnStart()
{
////Monsters appear
PlaySoundAtEntity("Thenameofyoursound", "Player", 0.1, false);
AddEntityCollideCallback("Player", "EndingArea", "Stahp", tue, 1);
}

void Stahp (string &in asParent, string &in asChild, int alState)
{
StopSound("Thenameofyoursound", 0.1);
///Yourcredits and other
}

I suggest you to invert my suggestion: If you escape, make the player see the cutscenes (like if the protagonist was remaining what happened to him), and, if you die, credits, as there's nothing to remain (you're dead)
