The band of killers in shockscape seemed the opposite of the deathlands six, (or was it seven?) and it would have been great to read more encounters with them as recurring characters. They would have been a capable thorn in the side of Ryan and the gang. They seemed so diverse and interesting, it was a shame that they perished so quickly.
I don't remember a band of killers in Shockscape.
But, then again, its been a loooong time since I read that one.
