The Origins characters return as well as Nikolai Belinski from the original timeline, who will be less willing to cooperate with the Origin's crew. The map also features a new duel wielded wonder weapon, called the GKZ-45 Mk3, which is a combination of the GKZ-45 and the new Ray Gun Mark III. Valkyrie Drone's serve as the new Hellhound round, and are also capable of turning zombies into Electrified Zombies, which stun the player if they are too close. The Russian Mangler Soldier is a zombie in an armored suit which acts in a similar manner to the Panzersoldat, although his health is not as great. The map also features a vast amount of new enemies for the player to combat. The Bridge is a new utility which can be used by the player to quickly move between certain areas of the map. The Electro-Shock Defenses return from previous maps, as well as the addition of three new traps, the Gigant Eye Beam Trap, the Flinger Trap and the Gigant Finger Trap, which are located in certain areas in the map, as well as a pair of mounted MG42's at Pack a Punch.

A dragon can also be ridden to Pack a Punch if the player completes the challenges needed for it. However, the player can safely go through it with the use of the Guard of Fafnir, which is an update on the Zombie Shield. The dragon functions in a similar manner to the Giant Robot's seen in Origins, where it will temporarily block off an area, which it does by breathing fire on it, which can kill the player if they stand in it for too long. The maps most obvious new element is the inclusion of Dragons in the map. Gorod Krovi contains numerous new features to the zombies mode.
