More than one hundred full-length BattleTech or MechWarrior science fiction novels have been published by FASA Corporation and later ROC, and have been translated into at least fifteen languages. The novels take place in the fictional BattleTech universe of the 31st and 32nd centuries and can be considered space opera. Catalyst Game Labs received the rights to publish both Classic and Dark Age book lines and has scheduled new works to resume in the fall of 2009. The Dark Age-era series, originally known as Mechwarrior: Dark Age, has been renamed Battletech: Dark Age.
