Mantic gives gamers what they want: the ability to play solo and to add zombies to Deadzone.
From the release:
Nexus Psi has been overrun by the Plague, and it’s everyone for themselves as the living dead wander the streets! Every faction must react to this new threat, fighting to free themselves before they are overrun. This supplement also introduces rules for solo play, enabling you to polish your tactics when no opponents are available!
