In case you still play GTA Online.
In case you are, for some reason, still playing GTA: Online, the online mode for Grand Theft Auto V that was launched two years ago, a little after GTA V itself, is currently having an event where players will get payouts of double the cash and RP that they ordinarily would- through select modes, anyway.
Apparently this is being done to celebrate the launch of the Executives and Other Criminals DLC pack that was launched yesterday; the bonus cash and RP can be availed in the Adversary modes, including the new Extraction mode, which sees teams hunting or rescuing a VIP from a downed jet. You can get as much as $30,000 in a single session- which is quite a bit.
Of course, GTA Online sucks, and is a never ending boring grind that locks away most of its interesting content, only for the interesting content to not be that interesting when you do get to it anyway. So there is also that to consider.
