Inventory is the abstract parent class of all actors that can be carried by Pawns. In rough terms, this is things carried by players: weapons, ammo, and so on. But Inventory classes are also used for things that aren't visible: for instance, when a player has special ability (some sort of power-up) this can be represented by them carrying a piece of inventory which is responsible for making changes to the player (such as adding a visual effect or changing the HUD or changing the player's properties).
Each inventory class knows what pickup can spawn it (its PickupClass). When tossed out (using the DropFrom() function), inventory items replace themselves with an actor of their Pickup class.
All of a Pawn's Inventory actors are in a linked list which uses the Actor -> Inventory property. Inventory is automatically destroyed when the actor carrying in is destroyed, or the player carrying it dies.

Tarquin: When a player dies, all Inventory actors he holds are destroyed. Any way to prevent this – either have them dropped, or have them remain owned in the player's inventory?
Recondite I'd look in MutUDamageReward and UDamageRules for dropping them, don't know about the other being that easy.
