GTA V is the sort of game that's best explored on your own time, really. But with a game so huge, sometimes it helps to have a helping hand point you towards carefully hidden secrets and Easter eggs, or maybe you might want a few tips on the best weapon locations, shortcut routes, and strategies for GTAO.
Maybe you're just looking for something to read on the loo?
Whatever the reason, you might be interested to know that the Brady Games guide for GTA V is half price over at Argos. Cheers jumpthegap!
