Instructions
Locate a bowling alley. There's one in south Broker, on the easternmost island. You can also find one in southwestern Algonquin. Enter the building when you arrive.
Go up to the counter to speak with the attendant. Choose either a five-frame half-game or a full 10 frames. It will cost $10 to play.
Walk to an empty lane to start bowling. Get Niko into position with the left analog stick. Bowl by pulling back the right analog stick, then pushing it forward.
