Grab

The grab ability is the in-game ability to pick up, move around and drop objects in Fallout 3 and Fallout: New Vegas. Unlike some other games where the player-character can move items in the game world (e.g. Gordon Freeman in the Half-Life series) there are no puzzles in Fallout 3 that require the use of this skill, and it is possible to play the entire game without using it and only miss out on some non-essential loot.

The implementation involves the Grabbed item hanging / dangling as if suspended from the initial grab point at whatever distance in front of the player it was when Grabbed (there is no animation of a hand or hands actually doing any Grabbing). The game world's physics apply to the Grabbed object, in so much as it will make a noise if knocked against another object, and a sufficiently hard knock can cause the player to drop the item.

The Grab function does not work while Fast Traveling (the item will be dropped where the player Fast Traveled from), nor does it work between map cells. Only some items can be Grabbed, whilst some cannot. Almost all items which can be put into the inventory can be Grabbed, notable exceptions including the Vault-Tec Bobbleheads, as well as some items which cannot be put in the inventory (such as Small Office Fans, Rollerskates, Globes, Alphabet Blocks). No container that the player can store things in (i.e. has an inventory menu) can be grabbed either, despite some of these being a lot smaller than objects which can be Grabbed.

Some uses of Grab include:
 * To make items easier to steal (moving them to somewhere where NPCs can't see the theft taking place)
 * To move a corpse so it can be consumed (with the Cannibal perk)
 * To access items in crates that are on shelves, preventing the player from looking into them.
 * To move things around for aesthetic reasons (e.g. redecorating the player's house).
 * To quietly move noisy obstructions such as barrels out of confined spaces like doorways and corridors where they may give away a stealthy player.
 * To kill an NPC by dropping an item on them causing damage. Doing This will not cause any hostilities.
 * Sometimes more valuable items are hidden at the bottom of containers below common or cheap items, and using Grab can save the player from having to Inventory and then Drop the unwanted items.
 * Stacking items to allow access to high areas normally inaccessible to the player such as Stockholm in Megaton, or the Preacher's perch in Seward Square.

An item can be grabbed by aiming at the item that needs to be picked up and then pressing the "Grab" key. By default, this is the right thumb stick on the Xbox 360 and PS3, and the Z key on the PC. Once Grabbed the item can be moved about using the right controller stick on a console or the mouse on a PC. Objects considered by the game to be heavier will be harder to move than light objects, which can lead to odd results when attempting to drag small body parts. To drop the item simply repeat the Grab command, and it will fall in accordance with the game physics.

In Fallout 3, the player is first instructed on grabbing items in the "Baby Steps" quest.
