Inventory

The "place" where all items that your character has are stored. Access it by pushing the "i" key during the game. In the inventory you can change the armor you wear, use drugs, load/unload weapons you have, and change your active weapons.

In Fallout and Fallout 2, during the battle access to inventory costs 4 action points, but can be reduced by perk Quick Pockets. In Fallout Tactics, access to the inventory is free, but various actions in the inventory cost you action points.
