'snatcher'; also known as the iron hand) was an ancient weapon devised by Archimedes to defend the seaward portion of Syracuse's city wall against amphibious assault.
These machines featured prominently during the Second Punic War in 214 BC, when the Roman Republic attacked Syracuse with a fleet of 60 quinqueremes under Marcus Claudius Marcellus.
When the Roman fleet approached the city walls under cover of darkness, the machines were deployed, sinking many ships and throwing the attack into confusion.
Historians such as Livy attributed heavy Roman losses to these machines, together with catapults also devised by Archimedes.
The producers of Superweapons brought together a group of engineers tasked with conceiving and implementing a design that was realistic, given what is known about Archimedes.
