Silent Death/Fallout Tactics

Silent Death is a perk in Fallout Tactics.

Effect
+100% if the player attacks a critter in the back while Sneak is active. As the perk only affects the initial attack and only applies to hand-to-hand attacks, the perk is functionally useless (especially since Slayer supersedes its effect). Backstab is its equivalent in Lionheart, while all games past Fallout Tactics removed it in favor of sneak attack criticals.
