The book itself is nicely produced, and up to the high production standards that Modiphius has established. Importantly, these rules can be integrated quite effortlessly within an RPG session or campaign without feeling forced or creating an artificial and awkward transition between systems. However, just to speak briefly about fights with ray guns, I have to say that the Red Alert miniatures rules do work rather well and compare very favourably with other sets of SF miniatures rules such as Rogue Stars. As such a GM can actually use this book to add to and create scenarios in a game where the ethos should be about technological, scientific, political issues rather than just be about fights with ray guns. The strong point of this supplement is that it does add to the game itself rather than being a bunch of ‘lore’ accompanied by charts and colour illustrations. I will confess that my heart sank when I learned that this book gave us a whole load of new technological devices, but importantly this section does more than give as a load of pseudo -scientific flannel, it includes advice and information about how these devices can be utilised narratively and how scenarios can be built around technological and engineering issues. Supplements such as this run the risk of being a whole bunch of fluff which while seeming to add colour and detail to the RPGs they support, have little positive effect on gaming experience. The book closes with Red Alert, which is a set of miniatures rules to be use with Star Trek figures which can act as an alternative combat mechanic in the game, or as an independent game in itself. This supplement also provides information on and for MACO characters: the Military Assault Command Operations… the army, in other words. We also have information on Star Fleet Intelligence and the rather sinister sounding Section 31: a particularly covert and morally abstruse element of Star Fleet’s intelligence service. The book includes a lot of colour text / lore/ fluff, call it what you will, on Operations Division and details on how you can create more detailed and specific characters who are from the fields of Engineering, Communications, and Security. What that means is information on the Engineering, Communications and Security wings of the organisation rather than the Command and Scientific branches. What we have in this book is fleshed out details and further information on the Operations Division of Star Trek’s Federation. I’ve already spoken very highly of Modiphius’ Star Trek Adventures RPG, and how it not only serves as a great role-playing system, but also evokes the atmosphere of Star Trek rather than being just an SF RPG in superficial Star Trek dressing, so I won’t go through all that again, but will focus on this supplement itself.
