If I die we ALL die (deadman's bomb trigger)

[atomic1fire]

Maybe as something not quite the same but pretty cool, you could have a suicide vest hooked up to a radio trigger instead. Your payload wouldn't be a bomb strapped to your chest, it would be a trigger strapped to your chest

Kill a guy and you might trigger a bomb in medbay, or cause all the escape doors to electrify due to some clever wire work. who knows.
