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.
it would be fun if there were civilians walking around, and if you shot them, they pulled out a pistol. That would be so cool. Just walking through the town and walk up to a guy and kill him with a flamethrower!
