  • This is the second transcendence weapon variant to be released for free through an event after Magnum Shooter.
  • The annoying bug with unable fire has been migrated from original Lycanthrope to this version. If player reload the gun while he`s aiming, bug will dissapear, but... The worst thing is SG552 Cerberus don't have scope aiming at 2nd mode, so this bug is insoluble.
