- ↑ Fallout: The Roleplaying Game p. 170: "X-cell was a general-purpose performance enhancer still being developed before the Great War. Development was never finished, but prototype versions were distributed through the black market and by scavengers after the War. It enhances all aspects of a user’s abilities for a few minutes, but it is extremely addictive, and the withdrawal symptoms are as far-reaching as the effects."
