1 comment 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 faggot can extract all of my scripts, read them and just comment the anty cheat out? Nothing, so there is the next point, I want at least a minimum saftey 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 alot 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 prooven 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 Update

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

Will there ever be survivor bots?

3aGl3 Mar 15 2014, 10:04am replied:

Actually no. If you ever looked at Pezbots, you'll notice that the bots are animated using weapon files for each animation. However I already have to animate the Bots and I also like to have some extra weapons. So in fact there isn't enough space to get human bots working properly.

Oh, I cannot connect to the RoZo servers, so I'll have to go solo I guess.

They will last in all following 0.5 versions, however, 0.6 is made up entirely from scratch, while 0.5 is based on the MP scripts.
