In our big news, C&C: All-Stars, will use a old-style Conyard-based building system! To my knowledge, this has never been done before in a Zero Hour mod.
The system, created by our own DetoNato, allows for creation of a Conyard system very similar to the one used in past C&Cs. No longer renaming dozers to MCVs, the system forces you to build within a specified radius of previous buildings. Additional MCVs can also be built. This allows for gameplay very similar to old C&C, and provides All-Stars, a mod aimed to uniquely bring C&C together in Zero Hour, with an added element critical to doing so.
The creation and refining of this system was something we have been working on the last few months, and we still need to sufficiently balance it. We will be keeping you all aware of our progress with it and the other aspects of the mod throughout the summer, and may be look for another round of beta testers soon.
Feel free to discuss this in the All-Stars forums.
