Transhuman is a player's handbook for Eclipse Phase, full of optional and additional rules and advice. Most importantly, It features two new alternative and simplified character generation systems for Eclipse Phase. One of these uses pre-created packages to build characters, and the other builds off that system but uses random elements to add twists. These systems are designed to make it quick and easy to create a new character or for gamemasters to whip up NPCs as needed.
Transhuman covers different types of Eclipse Phase characters in detail: AGIs, asyncs, infomorphs, uplifts, infugees, and indentures. In addition to roleplaying advice and optional rules for these specific character types, other elements of the game that affect characters such as insanity, death and memory loss, psychosurgery, nanofabrication, and reputation are explored.
The final section goes in depth on morphs. It starts with rules for creating your own morphs and then goes on to cover some brand new morphs to Eclipse Phase. It closes with a section on exotic and specialized morphs, such as flexbots, swarmanoids, aquatic morphs, and using bots, vehicles, habitats, and other non-traditional constructs as morphs.
