How to use a gamepad on PC? LEGO City: Undercover Guide

On the starting screen, right after loading the game, make sure that the first button you press will be a button on the pad

To play on a PC using a gamepad you should do the following two things: firstly, connect the pad to the computer before starting the game. Secondly, when the game is fully loaded, and the message "Press Any Key" appears, use any button on the pad. Otherwise, if you press a button on the keyboard, the game will not use the previously connected gamepad.
