In Assassin's Creed, what device lets subjects relive genetic memories?

In Assassin's Creed, the device that lets subjects relive genetic memories is the Animus.

The Animus is a fictional machine developed by Abstergo Industries. It allows a user to access inherited memories carried through a person's DNA, presenting those memories as an interactive simulation. The technology provides the narrative link between modern-day characters and historical protagonists.

Desmond Miles uses the Animus in the first game after being captured by Abstergo. Later games introduce different versions and operators, including the Animus 2.0 used by the Assassin team and the Animus Omega associated with later Abstergo projects.

The series distinguishes genetic memory from ordinary recorded history. Users do not travel physically through time; instead, they experience memories connected to ancestors. Extended use can also produce the Bleeding Effect, in which skills or sensations from a remembered ancestor affect the user.
