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 0.1 for Rocks 2 Rockets version 0. It is only a patch, you must have the full version 0 of Rocks 2 Rockets installed for it to be of any use. Instructions: 1) Extract the 7-zip archive to some temporary folder, or the desktop. It should create a folder called "Rocks2Rockets", possibly inside one called "Rocks2Rockets-Patch-v0.1" depending on how it is extracted. 2) The new Rocks2Rockets folder should be copied into the BtS Mods folder, the folder where Rocks2Rockets is installed. 3) Answer Yes, or "Yes to All", to the questions about overwriting things. This will replace 9 files, listed in the "Files in this patch" section of the included "Patch v0.1 Notes.txt" file and add that one file which has this (and more) information in it. When loading a save, if it asks to about doing a modifier recalculation I suggest skipping it. Nothing relevant to that has changed and it sometimes crashes (MAF type) on low memory systems.
