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 weapons from different game series. For infos about 0.5, a forum to discuss the mod and other things 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

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.

Help and Support

For help and support on the mod please visit our forum and make a post in the RoZO section rather then using the ModDB comments section!

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.

0 comments by 3aGl3 on Mar 1st, 2015

Hello everyone, today I got some small things for you.
First of all, we did some small updates on our RoZO server in the last two weeks which you may or may not have noticed. We did change the following:

  • Added a basic "meatgrinder" aka anti-stuck script, stuck zombies will now be killed after a few seconds
  • Added new weapon classes and sorted the existing weapons in accordingly
  • Completely rearranged weapons and other items
  • Fixed several small bugs
  • Removed several unused or redundant assets to save space

Now for the probably more interesting things, currently we are working on the authentication system as it is currently top priority so we can finally move on with the ranks and items given to a player.While we work on the ingame part of the login system we will also work on our website, the forum you can currently find at will be removed during the next weeks as we'll replace it with a website that will tell you in detail about our work. Also there will be a login section where you can manage your MTG account which will be used to store your RoZO rank data and similar.Even though we plan on introducing a bug tracker feature to that website you can also report bugs, here on ModDB, on our new Facebook page and on my Twitter. If you want to report a critical bug, please send us a private message to prevent abuse.

Stay tuned for more info on our new website, and of course updates to the mod.

You can download the mod from any server or if you like you can download a version here or for 0.6 here

Also we host a server with said version, running at this is currently the only place you can play it.

Also a little clarification again for everyone. 0.6 is a completely new build and we use a lot off stuff that currently needs a lot of testing, thus there is only one server at the moment.
Later on I will send the serverfiles to a few trusted people to host servers as well and evenutally you will be able to play the mod offline, on you own pc. However this will still take a alot off time.

Yes you are certainly right :)
It takes a lot of effort to make something big and you don't want it to get boring on you or else you'll lose your drive to continue.
