If you like futuristic energy weapons, come on in and take a read of this! It looks at disintegrators, disruptors, ion blasters, microwave emitters and sonic distruptors - all things hovering on the cusp of science-fiction and contemporary 'what-if' military weapons speculation. All are extremely deadly and high powered, and should be introduced to any game only with caution and after careful thought - someone armed with one of these is going to be well-nigh unstoppable, and if both sides have them it is time for mutually-assured destruction!
Each weapon is described clearly and concisely, and there are some good realistic illustractions. Game mechanics are handled well, and whilst they are written for the Mutant Futures ruleset it would not take much effort to translate them for other rulesets with which you are familiar.
The sonic disruptor is particularly interesting, as it can be used both for crowd control (its original design purpose) or in combat. They come in three forms: a grenade-style device you hurl at whoever you wish to be affected, a larger version that is shot out of a crew-served gun and the speaker-based type that has to be set up but is capable of sustained broadcast as it isn't dependent on an internal power supply. The effects are quite interesting, particularly in crowd-control mode, including 'dizzy' characters who move randomly as their balance and directional mobility is affected!
Neat but potentially game-changing... use with caution but have fun! You may want to make them tempremental, given to overheating or massively expensive in terms of energy expenditure, or find some other way of limiting their use as a means of maintaining game balance.
