To apologize for early issues with the GTA Online experience, Rockstar is giving away half a million in-game dollars to those affected. According to Rockstar:
You must play or have played Grand Theft Auto Online at any time during the month of October 2013 in order to qualify for the GTA$500,000 deposit in your in-game bank account.
Players will first have to install a forthcoming GTAV title update which we expect to happen next week. That title update (1.04) is expected to fix the remaining instances of issues that have caused vehicle purchase loss and will also enable the functionality through which we'll be providing this GTA$ stimulus cash to players.
We will announce at the Rockstar Newswire when each deposit is made.
Each of the two GTA$250,000 deposits will be made by Rockstar and should automatically appear in the in-game GTA Online bank accounts of eligible players. Beyond downloading the forthcoming title update mentioned above, there should not be any additional special action required by eligible players to redeem.
