  • This is the second transcendence weapon variant to be released for free through an event after Magnum Shooter.
  • The annoying bug where the firing animation does not perform, first seen on Lycanthrope, returns with this weapon. And since Cerberus used half zoom as a secondary mode rather than actual scope, the bug cannot be resolved by reloading while aiming down the scope like Lycanthrope.
