Examine the scepter to obtain the Red Jewel. This goes into the Bejeweled Box, which you can get in the Interrogation Room. Accessing this area requires the Club Key, so if you don't have that yet, keep progressing the story until you get it. Once you've got the Bejeweled Box, combine it with the Red Jewel to get the S.T.A.R.S. badge. You can use this item in two locations: the Underground Stairs in the Middle section of the Underground Facility, and the S.T.A.R.S. Office.
Whether you're playing as Leon or Claire, the solutions remain the same and can be accessed without grabbing the memo that hints at their solution. The only exception to this are the items you grab by developing film rolls--though, there is a minor exception even to that. Regardless, below you can find details on all the optional items locked behind safes, lockers, or hidden in the environment.
They are usually intended for use in public places, and intended for the short- or long-term private use of individuals for storing clothing or other personal items. Users may rent a locker for a single use or for a period of time for repeated use. Some lockers are offered as a free service to people partaking of certain activities that require the safekeeping of personal items.
Day use lockers are available throughout the facility and are the lockers that have hooks on them. Day use lockers are first come first serve each day. It is recommend that members bring their own lock (or purchase one from the service center for $7) to secure their belongings. Day use lockers must be cleaned out and the lock removed each night before closing. Items left overnight will result in the lock being cut and the items being logged in the lost and found.
Terry, there are many storage unit places closer to the airport, but then of course you'd have to rent a car. DIA Self Storage, for example, is less than 10 miles away. You can google map Denver International Airport, then "search nearby" for "self storage units" if you think that's something you might want to do. http://www.coloradoselfstorage.com/
Lockers are usually physically joined together side by side in banks, and are commonly made from steel, although wood, laminate, and plastic are other materials sometimes found. Steel lockers which are banked together share side walls, and are constructed by starting with a complete locker; further lockers may then be adding by constructing the floor, roof, rear wall, door, and just one extra side wall, the existing side wall of the previous locker serving as the other side wall of the new one. The walls, floors, and roof of lockers may be either riveted together (the more traditional method) or, more recently, welded together.
Tiers: may be specified as single-tier (full height), two-tier, three-tier, etc., meaning that the lockers are stacked on top of each other in layers two high, three high, etc. Tiers are commonly up to eight high; on occasion, even more tiers may be found, in the case of very small lockers for such purposes as storing laptop computers. The most common numbers of tiers found in lockers are, in order, one, two, and four; three-tier lockers are rather less common, and other numbers such as five, six, or eight even less common still - seven almost non-existent. Since locker cabinets are most commonly 6 feet (182.9 cm.) high (although there are exceptions), the height of individual lockers varies according to how many tiers are accommodated within the cabinet. The height of individual lockers is usually approximately 6 feet (182.9 cm.) divided by the number of tiers, so that two-tier lockers are about 3 feet (91.4 cm.) high, three-tier lockers 2 feet (61 cm.) high, four-tier lockers 1.5 feet (45.7 cm.) high, and so on. Standard features often vary according to the number of tiers: single-tier lockers usually include a shelf about a foot (roughly 30 cm.) from the top, and a hanging rail (sometimes with one or two hooks) immediately underneath that, at the top of the large compartment beneath the shelf; two- or three-tier lockers usually lack the shelf, but include the hanging rail; lockers with four or more tiers usually have none of these fittings, but consist of just the bare compartment.
