Nuts and Bolts

NOTE: While in game the capacity of the stores is stated to be 50, it is much easier to use a value of 500. Zombie (the person) originally scaled these values to match up to the 50 capacity. His (or her) notes and equations are below. It is more likely this is what the game uses as integer values are what's stored for the space of an item. See here

Space is the volume a single item occupies in storage. If you have 50 items with a space of 1 each, the group would occupy 50 space. Notice that aircraft, personnel and live aliens are not listed. These things require specialized storage facilities (Hangar, Living Quarters and Alien Containment) and do not use space in the General Stores. General Store facilities stack. Multiple modules act as a single cohesive storage unit, not as separate facilities. This is an important point to consider as you may be able to store more items in 100 units of space than 2 facilities with 50. For example, one General Store can contain 62 Stingray Launchers. If General Stores were not stackable, then two should hold 124. In actuality, two modules can hold a total of 125 Stingray Launchers. However when purchasing items, the game will 'round' to the nearest 10. Essentially so long as the space does not go over 509. For instance: there can actually be 63 Stingray Launchers in one module (63 * 8 = 504 < 509). Further examples: 2 Modules can contain 126 stingray launchers (126 * 8 = 1008 < 1010) (63 per module * 2 modules = 126) 3 Modules, however, can contain 188 (188 * 8 = 1504 < 1510), compare to 63 per module * 3 modules = 189 To determine how many items can fit in a base, simply take the storage space (say 1000 for 2 modules) and divide by the space listed for that item.

Zombie's Equations

Below are Zombie's equations using decimals and integer rounding. Simply divide the space listed above by 10 to get the amount of space an item takes relative to a General Stores having 50 capacity.

The "Multiplier" column is used for determining the quantity of items you can store in a module (It is simply the inverse of the Space column). As usual, integer rounding plays a role. The equation linking total storage space to the number of items is

Total Items = INT(Total Storage Space * Multiplier)

To illustrate,. assume we want to know how many UFO Power Sources can be contained in 2 General Stores. 2 General Stores have a total space of 100, while the UFO Power Source multiplier is 10/7.

Total Items = INT(100 * 10 / 7)
            = INT(1000 / 7)
            = INT(142.857...)
            = 142

These calculations only apply to items being transferred into a base. Items purchased are a little different. As long as your current General Store space is < total space, you can still purchase items. (Your current space level is found by multiplying the quantity of an item by its Space and then adding all those numbers together). When dealing with only a specific purchasable item, the equation for the maximum number of items possible is found using an IF-THEN statement.

IF (INT(Total Space * Item Multiplier) / Item Multiplier) < Total Space,
THEN Total Items = INT(Total Space * Item Multiplier) + 1

Example: How many Stingray Launchers (Item Multiplier = 5/4) can you purchase if you have one General Store (50 Total Space)?

IF (INT(50 * 5 / 4) / (5 /4)) < 50
IF (INT(250 / 4) * 4 / 5) < 50
IF (INT(62.5) * 4 / 5) < 50
IF 62 * 4 / 5 < 50
IF 49.6 < 50 (TRUE)
THEN
Total Stingray Launchers = INT(50 * 5 / 4) + 1
                         = INT(62.5) + 1
                         = 62 + 1
                         = 63

Notes

• Most weapons use up more space than their clip. Not the Heavy Plasma. Each weapon takes up 0.20 slots in the General Store, while a Heavy Plasma clip takes up 0.30.
• Craft Cannon Shells do not require (or use) any space in General Store inventory. As long as you have at least one open slot at a base, you could purchase (and contain) an infinite quantity of these shells. However, once General Store space is filled to capacity, these shells cannot be purchased anymore.
• Because of the integer rounding on each item type, you can store up to 19 of any item that takes 0.1 space (such as grenades) while still only using 1 of your store space, then from 20 to 29 it takes 2, from 30 to 39 its 3 space, and so on.
