Rockstar continues their trend of very little notice when it comes to XP events. The RockstarGames Twitter account
has announced that, starting yesterday, there is currently a double XP event going on for https://www.trueachievements.com/Max-Payne-3-xbox-360.htm
Players have until Monday morning (no time zone specified) to make use of the extra XP in their quest to complete training and hit level 50. Don't wait too long to make use of this as it takes many hours of playing, even on double XP, to hit the top level.
The Tweet also confirmed that there will be another 3XP event coming for Red Dead Redemption
later this month, although the exact date for this was not specified. Check back with us for more details when we get them.
