You need to make a multiplayer game.
If starting fresh : select multiplayer from the main menu. Create a private lobby. Then turn on the second controller and press a button (default being X). The second player should then join in split screen.
If continuing a save: load up the multiplayer save file. Once loaded, press start and select multiplayer. Once the screen is up, turn on the second controller and press a button. The game should then create a split screen environment and you can move characters around under the player icons to select who is controlling which character.
