The Dark Times is a Star Wars Battlefront II mod with a heavy single-player focus. It adds many new features to the game, including (but not limited to!) wave modes, randomized units, heroes, and skyboxes, and AI hero support. Its sequel, Rising Son, adds more of the above as well as several new maps and scripted missions.
This is the Dark Times II: Rising Son full download. Included in the .zip file is a readme.txt file, which should be read first. Also included is the full installer and a folder full of documentation for the mod, which can be read as the mod is installing. Please be sure to read all the pertinent information, and enjoy!
