We're not talking about pigeons, stunt jumps, glitches or Easter eggs either. We're talking about entire characters, whole missions, secret sex scenes and phonebooks worth of must-see trivia.

If you're a 100% completist, you already know about most of these. If you're a regular player, on the other hand, you need to go back. If you blasted through GTA IV in a month, you need to reload. If you never hunted a sadistic serial killer, dated a sex-crazed socialite or researched Lazlow's criminal history, you need to read on...



How many girlfriends do you have?

Everyone dates Kate and "Michelle" of course. With a quick visit to Love-Meet.net, Carmen the nurse and Kiki the lawyer are also easily found. Few players, however, bother tracking down the elusive fifth woman, Alex Chilton. She's snobby, picky, bratty, materialistic, self-centered and annoying. She's also totally worth the trouble.

Why? Because Alex Chilton, a perfect parody of Paris Hilton and

Carrie Bradshaw, is obsessed with documenting every meaningless minutiae of her own life. Which means - naturally - that she blogs. Which means that she will write about her relationship with Niko. Which means that she will write about her sexual relationship with Niko.

NB, you animal! The blog posts just get stranger and steamier from there, with Rockstar earning every bit of that Mature rating. You can even go on some bad dates, or dump Alex altogether, to watch the writing turn nasty.
