Help and Support

For help and support on the mod please visit our forum rather then using the ModDB comments section, as that has proven to be very confusing.

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. This can have several reasons and we apologize if the thing you absolutely love is along them.
One reason are engine limitations, COD4 has a lot of engine limitations and we can by far not use the resources we'd like to use. So we have to make decisions to keep the mod within the given limits.
Another option might be balancing, even though the mod is probably not balanced enough for versus play right now it's one of our goals to make that possible. We'd love to include modes where players can take the role of several zombies, very much like in Left 4 Dead.
And finally there are personal preferences, while I previously mentioned the engine limitations that counts for almost everything. And as this is our mods we as the devs can decide what content we want to have and what not, this is of course mainly personal preference.
Please respect that and also keep in mind that RoZo has more fans then just you so we can't include the wishes of everyone.

4 comments by 3aGl3 on Mar 9th, 2014

Finally I got some solid news on the new version 0.6 of RoZo mod.

RoZo v0.6 Public Release

First of all, there won't be a public release of 0.6 for quite some time, there are a lot of reasons for that, which I'll quickly mention in the following text. One of the probably biggest reasons is hacking in any kind, mainly rank hacking or the commonly known godmode, that can be used in private matches. As long as we don't find a solid solution to terminate it, there won't be a public release. But what does it take me to script for hours and get some kind of saftey on that end, when on the other end every fagot can extract all of my scripts, read them and just comment the anti cheat out? Nothing, so there is the next point, I want at least a minimum safety for my scripts, so long, no pub release again. Last but not least there has been a lot of trouble with the latest Release of 0.5 and also a lot of people did not seem to notice it at all. Also there are some smaller reasons we won't release a public version for now.

RoZo v0.6 Official Server

Of course it's important to provide enough servers for everyone to play 0.6, also we have to rely mainly on the feedback of players for bugfixing, as we do not have the time to playtest the mod all day long. For now the server we hosted has proven to be enough in capacity, however for players that are not from Europe it has a pretty high ping. If anyone feels confident enough to host a server on another continent, feel free to contact me, however this is NOT a easy option to get the server files, as I'll not just send them out instantly.

RoZo v0.6

Currently we're working on the next, very big, Update for RoZo 0.6, on the end of this post I'll again put the latest changelog and update it at times. However it should be noticed, that the update isn't even close to the 50% mark as of now. Even when I'm done with all weapons that will not be close to half of it. However no preview or anything will go online before a few things are settled.

RoZo v0.6 Update ToDo

Of course I can't go without telling you what we have planned for this update, so here is a quick List of things.

  • All new weapons and attachments
  • All menus in a custom style
  • Optimized maps (of course not all at once, 0.5 currently features around 100 maps)
  • New zombie AI
  • Reworked gamemodes
  • New playermodels and proper female models
  • A few other things

RoZo v0.6 Update Changelog

The changelog previously shown here is obsolete for the most part again.

hey i was wondering, wether the version 0.5 will have any more updates to it, cause as of right now v0.5 is much more fun to play on cause its more function-able and has full features e.g ranks etc.

As said in the description of the download for 0.5.021 there are no more big updates planned for v0.5. We're currently aiming for some bugfixes though, also we might consider giving a few ideas, you guys posted, a chance and add them to the mod.
Of course we're trying to add the missing features for v0.6 as fast as possible.

that is great news, also i was playing 0.5 today and i realised whenever i get the RC-XD and use it - my secondary weapon disappears (in this case my ballistic knife) also when i use the RC-XD my previous care packages and kill streaks also disappear - a fix for this is much appreciated - thank you.

I kno, it sounds stupid, but why not add some ww2 weps?
Garand for example? It's gonna be cool.

3aGl3 Oct 27 2013, 9:11pm replied:

I can't add an unlimited amount of weapons and I guess a lot of people like the modern weapons more. M1 Garand is a fine gun, so is Thompson and a lot others but they also don't really fit into the mod...

Oh. I wanted to ask about weapons.
Damn. That's sad.
