How to Pick Stuff Up in "Grand Theft Auto 4"by Andy Smith ; Updated September 22, 2017
"Grand Theft Auto 4," released for Xbox 360, PlayStation 3 and PC, gives players the ability to pick up weapons and other items. This task can be done while on foot rather than while driving. Each version of the game features its own control scheme for completing this task; all however, require players to be beside the desired item.
Press the "L1" button to pick up an item in the PS3 version.
Use the "Left Bumper" button for the Xbox 360 version.
Press the "F" button for the PC version.
