Doomsday Machine is an automated, deadly trap - an intelligent security system protecting a secret base hidden in the radioactive wastelands. Its algorithm commands it to destroy any intruder, whether it is a man, mutant or a Moloch robot. What could be hidden behind such a powerful defense system? Doomsday Machine 3.0 is a reimplementation of an extra army, which was given away as a freebie at Spiel 2007. Essential skill of that army (which contains only shooting units) is the ability to redirect shots and rotating units (once per turn). It was included as the fifth army in the English Z-Man edition of Neuroshima Hex! 3.0. In Poland it's available separately only in limited copies.
