Heavy Gear is a roleplaying setting that uses the SilCore ruleset. It is also a miniatures wargame.
Heavy Gear is set in the year 6000AD, on a planet called Terra Nova, which is an ex-Earth colony. Separated from Earth by many thousands of light-years, travel is made possible by the use of gateships, which open a Tannhauser Gate, massively shortening the distances between habitable planets.
After colonisation and settlement, the Earth government, wracked by internal strife, pulled its massive and expensive gateship fleet back to Earth to avoid having it lost in the interplanetary cili war. Terra Nova was thus cut off from Earth.
It has just been re-discovered by a stronger, neo-fascist Earth, with designs to use its armies of genetically-engineered supersoldiers and hovertanks to take the colony back by force. Against this new threat, the Terra Novans use their armies of Gears, or mecha, supported by landships and striders.
