We could go a long process of doing request to get items, or we could do the fast way.
The fast way is to add up your requests from each person and then add twenty-five. That is the total request the group has.
Sniper Rifle = 11
Assault Rifle = 6
Sub Machine Gun = 3
Pistol = 2
Revolver = 0
Shotgun = 1 (for pellets), 2 (for balls), 4 (for slugs)
Light Melee Weapon = 1 (no effect on equipment slot)
Medium Melee Weapon = 2
Large Melee Weapon = 4
Bullet Proof Clothing = 2
Bullet Proof Vest = 1
Military Armor = 2
Advance Armor = 3
Helmet = 1 (adds to armor)
Shield = 2 (adds to armor)
Kits = 3 (aids you in three skills), 4 (aids you in three skills and has no effect on equipment slots)
Trinket = 2 (aids you in one skill, but has no effect on equipment slots)
The numbers are how much it cost in terms of request to get.
