Social Media Manager Jeff Rubenstein shared the following via PS Blog:
You've probably already heard the news: this coming Monday, October 27th, there will be an update made available on the PlayStation Network to unlock the entire Trophy system for Grand Theft Auto IV on PLAYSTATION 3.
Rockstar Games asked that I share a bit more info with you.
Make sure to download and install the update before playing in order to start attaining Trophies. There will be 51 total trophies, broken down by four different levels: bronze, silver, gold and platinum - all contributing to your overall experience level on your PlayStation Network profile.
Among the 51 trophies to be released Monday, look for:
One Man Army - only those that are wily enough to survive a 6-star wanted level for a full 5 minutes will be rewarded with this one.
Dare Devil - an award for those who find and execute all of the Unique Stunt Jumps throughout Liberty City.
Chain Reaction - an Achievement for those who can pull off blowing up 10 vehicles in 10 seconds or less.
Liberty City Minute - for those that have completed the game story in less than 30 hours. As the Social Club's Story Club leaderboard can attest, this is not an easy feat.
Look for detailed information on all 51 trophies to be revealed at http://www.rockstargames.com/IV/multiplayer this Monday when the PLAYSTATION Network update goes live.
See you back on the streets of Liberty City this Monday! More PlayStation 3 News...
