The Rockstar Games Social Club now displays the GTA IV multiplayer leaderboards that were previously only visible in game.
All the online multiplayer statistics found in the game Stats screen are now accessible via the Social Club. You will also be able to see how your multiplayer cred measures up against everyone else by bringing up side-by-side comparisons.
To view the standings, click the GTA IV in your profile box and then select the multiplayer badge. A table of users will appear with ranks and other information. The data has plenty of filtering and sorting options to keep you busy for a while
