From the back of the book:
In a world that is filled with super-powered heroes, super-dangerous mutants, and super-deadly villains, what's an everyday criminal or multi-millionaire to do?
Get a Weapon. And fast.
Available weapons include:
Battlesuits, from S.H.I.E.L.D. body armor to the latest fashions for IRON MAN; the powered weapon suits of the United States and Soviet Governments; weapons, from cheap handguns to atomic-tipped missiles; special weapons, including the mighty shield of CAPTAIN AMERICA and the awesome arsenal of arrows of HAWKEYE the archer.
This accessory describes the various vicious devices used by villains and heroes, so you can send in the MANDROIDS at a drop of a helmet.
Because you never know what the well-dressed villain is wearing this year...
WEAPONS LOCKER is a game accessory for use with the MARVEL SUPER HEROES role-playing game, and contains a 32-page sourcebook of battlesuits and individual weapons used in the MARVEL UNIVERSE.
