I can't say it's one of the spudiest ways I died, but it was indeed one of the most spectacular that I have made.
During the last mission of the bad ending of Wing Commander III where I must repel an unwinnable assault against dozens of Kilrathi fighters and cruisers. I am finally out of missiles and decides to plunge within the belly of a Kilrathi Dreadnaught, just to see its lauching hangar.
I succeed to pass through and as soon I get out of the other side, I got shot by the Dreadnaught Turrets.
Well, in fact, it was a real stupid death...
