The inventory system combines traditional slots with an encumbrance system based on the weight of the objects carried. Every player has sixty-four slots in their inventory and also a maximum allowed weight that is determined by his or her Strength. A character may have available slots but still be unable to carry an item if it exceeds his or her weight allowance. The best way to increase what you can carry is with a vehicle, as everything from motorcycles to dune buggies will have inventory slots.
Inventory slots also determine the weapons you can quickly equip during combat. Every character has slots for six equipped weapons with associated hotkeys, so it only takes about a second to switch between weapons in a pinch. Swapping out armor is a bit slower, as it requires opening the inventory window and dragging items in and out of the character profile or double clicking on the item.
Characters also have a personal stash that they can access from any of the three types of vaults located in the world (Sector Vaults in any town, Barter vaults in Barter towns, and Banker Vaults that are accessible only in special Banker towns). If you are a member of a Clan, sometimes you can have access to a Clan Vault.
