Return of Zombie Ops is a zombie modification for Call of Duty 4, it features content from Black Ops Zombie mode as well as from Modern Warfare 3 Survival mode and Ghosts Extinction mode. It's set slightly in the future with a lot of new weapons.
For more infos about the mods different versions visit:

Main features off the mod

  • Different Zombie (PvP and PvE) Gamemodes
  • A big arsenal of new weapons
  • Character customization
  • New rank system with 10 Prestige ranks
  • Challenges for extra money, XP and items
  • Skill trees for a more personal character

Versions and Releases

There are two versions off RoZO planned, first we got the normal version. It will include all off the features that we put into RoZO. Second we got the light version, this version won't include new weapons, and perhaps also some other things. The light version is mainly meant for people with slow Internet and to keep up compatibility with the default CoD4 1.7It is planned to release the light version a few days after the normal version since we will need a few days to update it.

Setting & Background

In RoZo a military special force tries to get control over the zombies outbreak that started by accident in a testing laboratory. You take over the role of one of the field soldiers, you have to face the zombies armed with anything that's available. The HQ will send you objectives and support during the mission.

Abandoned/cut features

If you are following RoZO for a certain amount of time now you have sure seen a lot of features being announced and later disappear again. Of course we'd like to keep as much as possible in the mod but that's just not possible.
One of the options if that a feature/item is not fitting the concept of the mod or interfering with other things.
Another, and probably the one we encounter most of the time, option is that COD4 has certain engine limitations, that we can not work around nor influence in any way at the moment. So we have to create a mod within those engine limitations. To do so we have to abandon certain things to make room for new or just to be within the limits. If a thing you absolutely loved is among the abandoned stuff we're sorry but please keep in mind that there are also other people who want to enjoy the mod, so not everyone can have his favorite stuff.

Hi, once again i got some good ideas :D :-
1- Power ups from fallen zombies(just like from Black Ops 2) like instant kill, Max Ammo, Kaaboom(Nuke) With its special sounds from black ops 2
2- Porting or re-making maps from Black Ops 2 zombies will be so awesome, with its stuff, like doors, barriers, parts, secrets, even porting the map (turned) where you play as a zombie, is also cool, simply saying that, the much this mod is similar to Black Ops 2 zombies, the more its awesome
3- Making the Mod's main menu like Black Ops 2 menu(i mean the earth that turns around, also making the maps list on the earth like Black Ops 2.
Maybe i am asking much than possible, so once again i say, making any of these things would be cool :D.

Also the Mystery box should be like Black Ops 2's box, one and only model, with respect, i think all the mystery box models in the mod are stupid, except the default one(that looks like a real armory).

please stay patient a few more days, I'll shortly upload part 2 and part 3 of the mapping tutorials, including all the details for RoZo maps as off now.
Artillery strike is a little weird at times, hitting in mid air and all that...appears on all maps and seems to highly depend on the selected location.

For skybox height I suggest at least 5000units over 0 (when you place an entity and it has x y 0) due to the AC-130 Gunner Streak that follows, the higher we can put the guy the more real it feels :)

Hi, after playing Black Ops' multiplayer and zombies, i have some ideas:-
-A BO2 like create a class theme(its cool)
-Adding some darkness to the maps to give them a terror feeling( the current maps with a bright sun doesn't make me fear anything unlike BO2)
-Adding some terrible zombie sounds from BO2 like making the last zombie make a weird and scary noise+ zombies on fire(again like BO2)
-Customizing killstreaks (choosing some of them not give them all, and making killstreak points that will be given wen the player ranks up a level until the killstreak menu is all unlocked)
-Some new killstreaks like K9 unit(sending attack dogs to fight with you)
Even doing one of these things would be pretty awesome (if it is already makeable :P).

Heh, not sure about Score-/Killstreaks yet. As I said soke time before, dogs aren't very likely to ne added for the human faction.

But they are fun :P , RC-XD is cool, its good to know it will be added, but what about DragonFire, A.G.R , or even Hunter Killer? Oh ****, i asked more than you can do :P , anyway again, any of them is awesome, knowing that even BO2's zombies had no killstreaks :D
