Trip-wire bomb casings were a component that was used in the crafting of bombs by Ottoman Assassins, that triggered an explosion when a guard or a civilian stepped on the wires which the finished bomb was set with.
As the wires needed to be planted into the ground, they took 3 seconds to arm, and were best used to eliminate roaming patrols, as well as proving useful when placed in a trap location. For instance, as some Templar Den captains fled when they spotted the Assassin Ezio Auditore da Firenze, a lethal trip-wire bomb could be placed on their route back to their hiding place.
In terms of bomb-crafting, trip-wire casings could be used in conjunction with any gunpowder type or ingredient.
- Ezio and his allies were the only characters who did not trigger an explosion once they passed over a trip-wire bomb. Presumably, this could be explained with their experience of spotting and setting the bombs.
- Due to this, civilians could set off a trip-wire bomb, disrupting Ezio's plans, which should have been taken into consideration whenever he placed one.
- Trip-wire bombs also featured in the second stage of the Animi Training Program and the Animus games console as an ability, though they are limited to dazing those caught in its effect for a short while.
- A variation of this bomb type, known as trip mines, were used by the Assassin Ratonhnhaké:ton during the American Revolution.
