Eclipse Phase - Titanomachy
Eclipse Phase is a unique series in that it is available for free in pdf form from its creators. you can find many of them here: Rob Boyle’s Blog
Though there are many other books available, I would caution against reading the game mastering sections in order to avoid spoilers on the setting.
Once you’ve downloaded the core rule book you will be mostly good to go. It is suggested that you go ahead and roll up a character ASAP, as you’ll need to have it uploaded to here before the first adventure.
The only thing non-standard to the character creation, is that once completed you will gain an additional 5 RP. (Those who completed the Continuity session keep whatever rewards they gained from that.)
