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 fitting.
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. 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.

Hey everyone I'm here with some very short news.
An alpha preview server of RoZo 0.6 is up on, the password has been removed and the server is now public.
Feel free to drop by on the server and test out the mod, however the majority of features is still missing and there are bugs everywhere.
If you want to help us pushing the mod forward please sign up on our forum and report bugs to us.
I'll soon update the change log and a list of already known bugs.

The old versions had "Nightcore - Whispers in the dark" while 0.5.028 had "Metallica - For whom the Bell tolls" if I'm not mistaken.

Please make a puplic version of the mod that one can download from the site with the specific version of the mod not able to connect to online servers but offline LAN servers only or something so that hackers can be avoided online. I also LOVe to make a LAN party with 4 or 5 of my friends at home, so PLEASE just try :)

Eventually I will, for now it'll stay on our server only. Also before anyone asks, the server is down for maintenance and will be back online as soon as we resolved the spawning issues.

#AdvancedWarfareMP looks just as bad as the rest I've seen of the game. Seriously, buy Titanfall if you want that kind of game...
