I don't have the CTE, but one of my friends who has it told me that he heard there are four new weapons coming to the base game themed after the Four Horsemen of the Apocalypse. Apparently they have difficult unlock requirements, and are the Annihilator M18 Trench & Factory for Assault (the Blood), the Meunier A6 Factory & Optical for Medic (the Epidemic), the Burton LMG Storm & Optical for Support (the Hunger) and the Berthier M1916 Carbine & Marksman for Scout (the Murder).
If this is true it sounds really exciting, but can someone who has the CTE confirm this? He did tell me wrongly that Apocalypse had an Operation so I'm not sure. Thanks.
