Rocks 2 Rockets is a mod-mod of Caveman 2 Cosmos. It has been trimmed down with the aim of getting it playable through the end of the game on a significantly less capable system than is required by C2C. It is still a large mod, just less demanding than C2C. There have been some adjustments for balance purposes. There have also been a few modifications for other reasons, and perhaps a bug fix or two that is not yet in C2C. The entire "galactic" era has been cut out, as has much of the "transhuman" era. Less drastic cuts have been made across the earlier eras. Features supplied by the game engine as of C2C version 26 are all present, including the viewport functionality, as well as many later bug fixes, AI improvements, and optimizations. R2R has a topic in the mod-mods subforum of the Caveman 2 Cosmos forum at the Civilization Fanatics' Center.
This is patch version 0.4 for Rocks 2 Rockets version 0, 0.1, 0.2, or 0.3. It is only a patch, you must have the full version 0 of Rocks 2 Rockets installed for it to be of any use. You do not need to have the earlier patches installed as this patch also includes everything that was in those, but it will install fine if you do have them.
Note: Installing this will overwrite the settings available via the BUG menu and any customized screens such as in the Domestic Advisor. If you have changed these settings and want to keep them: before copying the new Rocks2Rockets folder over the old one you should save a copy of the files in the Rocks2Rockets/UserSettings folder. Copy them back into the mod after installing the patch to get your settings back. They are all user preferences which can be adjusted at any time.What was changed in these user settings files (most from before v0.4, some v0.4 tweaks):
Advanced Scoreboard.ini: scoreboard set to show a max of 33 players, was 30.
AutomatedSettings.ini: automated hunting set to only attack if the odds are at least 85%, was 50%.
Better Espionage.ini: "show calculated information" enabled for the espionage screen(changed for v0.4).
CustomDomAdv.txt: domestic advisor has had a new screen added just for properties, showing the current amount and change from last turn for all of them, and some minor adjustments to a couple of the existing screens. The new properties screen now also shows the the thing being built and turns to completion (changed for v0.4).
RoMSettings.ini: RoM setting for dynamic XP is turned off and the setting to allow multiple religions to spread into cities on their own (without missionaries) is turned on. (Both changed for v0.4.)
It will replace many files and add several new files, all listed in the "Files in this patch" section of the included "Patch v0.4 Notes.txt" file in the extracted Rocks 2 Rockets folder.
The new map script is a version of Erebus map from the Fall from Heaven 2 mod which has been adjusted for R2R's terrains(and slightly tweaked in some other ways).
