The Terminator RPG Core Rulebook

Publisher's blurb: You play resistance fighters struggling against the machine onslaught of Skynet in an alternative and post-apocalyptic version of today—the once "far future" of the 2020s. You can take the role of rebel time travellers sent back to various points in time to stop Skynet from altering history. You can even play natives of any historical time period, targeted by Terminators and trying to stay alive as a future hell is unleashed around you.
