Dynasty Warriors

Dynasty Warriors is a violent, combat-based video game series published by the Japanese company Tecmo Koei.

The game was a favorite of Adam Lanza, a young mass murderer who killed 26 people, including 20 schoolchildren, at an elementary public school in Newtown, Connecticut, on December 14, 2012. Lanza did not have a known criminal record and the authorities have not disclosed what he was doing on his computer in the days and hours before his murderous rampage.

Lanza reportedly killed his own mother first before driving her car to the elementary school.
