Colloquially known as the '''''1990 Update Flyer''''', this booklet does not appear to have a proper title. It was released by [[FASA]] as a free advertisement handout to promote the [[BattleTech]] universe in 1990.

It is eight pages including the front and back cover.

==Contents==
* BattleTech, a single paragraph overview of the universe.
* The Inner Sphere, a three paragraph overview of the [[Successor States]] circa [[3050]].
* The Star League, a six paragraph history of the [[Terran Alliance]], and the rise and fall of the [[Star League]]. 
* The Exodus, an eight paragraph overview of [[Aleksandr Kerensky]]'s Exodus and the [[First_Succession_War|First]], [[Second_Succession_War|Second]], and [[Third_Succession_War|Third]] Succession Wars.
* The Clans, a five paragraph overview of what little is known of the [[Clans]] circa 3050 and the varied [[Inner Sphere]] responses.
* MechWarriors, a three paragraph overview of the neofeudal role of [[MechWarrior]]s in the Successor States.
* Mercenaries, a four paragraph overview of the role of mercenaries in the Succession Wars.
* NEWSWORLD, an interview with [[NAIS]] Systems Engineer Dr. Marie Lucas, who explains the basics of BattleMech construction and key systems, as published in the March 3038 issue of NEWSWORLD.
* The Clan Invaders, an overview of what is known of the Clans, including:
** Organization, a one paragraph overview of the Clans' [[Point]] and [[Star]] formations for BattleMechs and infantry.
** Combat Equipment, a three paragraph overview of Clan technology, including ''[[Toad]]'' battlesuits, superior armor and fire control systems, and lighter, smaller, and more efficient equipment.
** Tactics, a nine paragraph overview of Clan combat doctrine, including the ''[[batchall]]'', bidding, avoidance of physical attacks, armored infantry, tendency to fight at a numerical disadvantage, one-on-one fighting style, and recommendations that Inner Sphere forces try to use numerical superiority and ambush tactics.
*Products, the final section advertising some BattleTech products complementary to the Clan Invasion era:
** ''[[BattleTech,_2nd_Edition|BattleTech Boxed Set]]''
** ''[[Technical Readout: 3025]]''
** ''[[MechWarrior: The BattleTech Role Playing Game]]''
** ''[[House_Steiner_(The_Lyran_Commonwealth)|House Steiner]]''
