Core Mechanic	Roll d100 at or below a skill percentage or a statistic multiplied by five. Successful doubles and 01 are critical successes; failed doubles and 100 are fumbles. In opposed tests, a critical beats an ordinary success, then the higher successful roll wins.	Roll d100 and try to land equal to or under your skill (or aptitude × 3 for unskilled checks), adjusted by difficulty modifiers in ±10 increments. The 33/66 rule grades each roll on a single throw: a success of 33 or higher is a superior success, a failure of 66 or lower is a superior failure, and doubles (00, 11, 22, …) are criticals. Four pools, Insight (mental), Moxie (social), Vigor (physical), and Flex (wild card), spend to add +20 to target numbers, flip-flop a roll's digits, upgrade a success, ignore wounds or trauma, or introduce narrative elements like NPCs and environmental details.

Best For	Groups who want modern investigative horror built around dangerous assignments and the relationships agents sacrifice to keep their work secret.	Groups who want hard transhumanist sci-fi with cosmic horror undertones, dense subsystems for hacking and body-swapping, and the Firewall conspiracy framework where cortical-stack backups turn death into a setback rather than the end of a character.
Highlights	Expertise can reveal clues without a roll when agents have time to investigate. Bonds let agents reduce sanity loss by damaging relationships they depend on. The core pair provides threat-building procedures and a complete operation with pacing tools and several possible outcomes.	The ego/morph split separates mind from body: characters back up their cortical stacks and can resleeve into biological morphs, robotic synthmorphs, or digital infomorphs between sessions, making body choice a tactical decision and death a recoverable setback. The 33/66 rule grades each percentile roll on a continuous scale of superior success or superior failure without rerolls, so a single throw produces a degree of outcome rather than just pass/fail. Seven distinct reputation networks (@-rep, c-rep, f-rep, g-rep, i-rep, r-rep, x-rep) replace cash for many transactions in post-scarcity territory, modeling factional standing as a parallel economy with its own favor limits and weekly refresh caps.
Considerations	Combat can kill an agent abruptly or leave permanent injuries. Sanity loss can force behavior outside the player’s control. Handlers must prepare the mystery and judge what evidence the agents can uncover.	Bookkeeping splits across an ego sheet (mind, skills, traits, pools, rep) and a separate morph sheet (body, ware, Durability, derived combat stats), and resleeving mid-campaign swaps out the morph half including pool maximums. The book takes an overtly political stance: the introduction states it is "not the game for you" if you support authoritarianism, and faction writeups present anarchist and autonomist values as the authorial baseline rather than one option among many. Routine cortical-stack backups make character death recoverable by design, so traditional life-or-death stakes need to be reframed around backup destruction, exsurgent infection, or memory lack to carry weight.
