If you've just got GTA 5 for free from the Epic Games Store and you're jumping into GTA Online for the first time, get ready for some big differences. GTA Online is a packed multiplayer experience with almost seven years' worth of updates. It's a big, complicated game with an absolutely dizzying array of vehicles, businesses and activities to check out.
Crucially, too, you're sharing the world with up to 29 other players, which takes a big of getting used to. GTA Online will eat as many hours as you want to put into it, with deep progression systems, loads of expensive properties to buy and tons of vehicles to collect.
