This is a fan-made patch for The First Encounter and The Second Encounter that includes lots of enhancements and new functionality for the game client, dedicated servers, tool applications and even gameplay logic. Despite this, it's perfectly compatible with vanilla servers and user-made content.
The goal of this project is to enhance user experience, as well as provide new ways of modding the games and, of course, play them.
See Classics Patch wiki for various information about the entire project.
