Captain Kwok's Balance Mod

The Balance Mod aims to provide a set of balanced data files for Space Empires V in keeping with the stock game along with competent and competitive AI opponents.

Captain Kwok IconMod Overview

Captain Kwok's Balance Mod Logo

Work on the Balance Mod began in August 2006 with the goal of creating new standard data files for Space Empires V that were balanced and in keeping with the Space Empires series. A number of SE:V beta testers helped with the initial direction of the mod, providing helpful feedback and even a few files. Since then, the work has continued for more than a year as lots of suggestions and comments from the Space Empires community have kept me busy tweaking and improving the mod. Hopefully the Balance Mod addresses most of the issues in the standard game and adds to the Space Empires experience.

Check out the feature list below for a brief summary of the main changes that were made. I'm always working on the mod and keeping it up to date with each SE:V patch and not to mention the fact that there is always something to improve - especially with the AI!
