( MAYHEM PVP )
40-Player FFA (Free-For-All) PvP Gameplay where every player kill grants 1 Store Credit. This mode also features World Events that will change gameplay and offer ways to earn even more Store Credits!
This video teaser depicts one of the world events that can occur during a Mayhem PvP match. This quest has a wild male T-Rex appear and unlike other Players who only grant you 1 Store Credit per Kill, a boss kill like this grants a percentile (based on damage) of 100 Store Credits! So when you see a World Event like this make sure to head to it and claim your reward!
