by the fact that Kra'vak pass through several gender and behavioral stages as they age which make them somewhat unpredictable as members of one stage are more aggressive and territorial than those in another stage. Kra'vak technology is similar to humans, but in some cases they are not as advanced. They favor powerful non-energy based weaponry such as railguns and missiles, and they also lack shield technology. Sa'Vasku — The Sa'Vasku are extremely long-lived semi-aquatic lifeforms resembling giant nearly-immobile jellyfish. They are an ancient race that has seen many space-faring species rise and fall. Little is known of their race except for the fact that they seem obsessed with balance and are fearful of change. They believe young space-faring races like humans are too naive to be left unchecked and they ruthlessly oppose their expansion into space. Sa'Vasku technology is biosynthetic and their spaceships are alive, genetically created and grown for specific purposes. Their construct ships are equipped with various "weapon organs" that generate energy beams or launch spore projectiles. Phalon — The Phalons are a carbon-based, oxygen-breathing species, somewhat humanoid in physique however they have multi-jointed limbs, exoskeletal hides and flat triangular-shaped heads dominated by single tri-lensed eye. They have three sexes, fertile males and females, and a more numerous asexual group that comprises most of their military force. Like the Sa'Vasku, Phalon technology is bio-synthetic in nature however they use genetically grown materials like humans use metal and plastic, building snail-like spaceships that are made from organic components but are not "alive" in their own right. The Phalon thinking-process is similar to humans, and the two species can carry on meaningful conversations, however Phalons are completely amoral. They take what they want without considering payment, and do what they wish without any regard to consequence. Overview of game mechanics Full Thrust (FT) uses six-sided dice, or d6, for all combat resolutions. Typically, a game of FT requires many six-sided dice. In the version 2.5 rule set, measurements in FT are based on Movement Units (MU), which can be equal to whatever measurements the players wish to use. Usually they are either inches or centimeters, but this depends on the sizes of the models used and the size of the battle board. Normally, rulers or tape measures are used to measure distances between models, as in most traditional figure-based wargames; FT can also be played on a hex-printed battle
