The Hysteria has so far only appeared in the BattleTech (Video Game) by Harebrained Schemes LLC. This source does not meet the current criteria for Canon, and is thus treated as apocryphal at this time.
Incumbent Line Developer Randall N. Bills explicitly stated that it was the intention for this particular game's storyline to be fully canonical. That means that if and when the finished game is released, any information it contains about the Hysteria will likely be declared canonical.
