Twilight: 2013 (2008)

Publisher blurb:

Twilight: 2013 is the licensed third edition of Twilight: 2000, GDW's classic roleplaying game of gritty military conflict and grueling daily existence in the devastation of World War III. This core rulebook provides a complete setting in which players can take on the role of any survivors of the end of the world, from soldiers fighting the desperate last battles of the Twilight War to ordinary men and women struggling to rebuild shattered lives and cities. The staged complexity levels of the Reflex System, Twilight: 2013's all-new game engine, allow gamemasters to balance speed, detail, and lethality according to their own preferences.
