I have also just posted my review of The Penal Zone as promised:
Alternative Magazine Online:
"Overall, this is a strong start to the new series of Sam & Max. The beginning seems confusing at first but then pays off. The new controls agitate initially before soon becoming second nature. Finally, the vocals talents of David Nowlin and William Kasten never do any less than live up to the larger than life personalities of Sam & Max. I laughed out loud constantly whilst playing for the five hours or so that The Penal Zone lasted. The music is, as always with this series, a jazzy delight."
