The Watts-MacLeod strain is a strangely benevolent version of the exsurgent virus, seeming to imbue its victims with psi abilities without any of the other transformative elements typical of other strains. Perhaps created as an accidental mutation of the exsurgent virus, there are many who wonder if the true detrimental effects of this strain simply have yet to reveal themselves.

Though infection with this strain does provide some bene ts to the character, the gamemaster should make sure to play up the creepy and unsettling nature of this virus. The character should never be certain that they haven’t in fact been subtly influenced by the virus in ways they can’t immediately pinpoint—they should always feel like the axe may fall at any moment.
