|Trophy: World Wild Fight|
|Complete 'Defeat marauders in arena'|
The PlayStation 3 and Vita versions of this mission are related to a trophy named "World Wild Fight", completing this mission will reward you with a bronze trophy.
You'll start with the Vulcan Fury, although it's not very practical for this mission so refrain from using it and spare the ammunition. The arena is a large wide open square with only the other rim and a + shape in the entrance safe to be walked upon. Pick up the ammo in the center to begin the challenge; to kill 30 marauders. This time they're equipped with newer weapons that fire a shot when they do their standard leap and slash attack. The downside is the small walkways and four possible directions means it is hard to properly dictate where they are coming from.
So revert to the use of the Beam Reflexor (the Wave Concussor lacks the range here) and the old aerial wastelander mover to hit all possible targets all around you. Eventually the arena's alarm will go off signifying the submerging of the arena into lava. Jump on either of the four large platforms that will simultaneously rise up in the corners of the arena to avoid the lava.
After killing 30 marauders a cutscene starts, leading into the next mission: "Destroy eggs in nest".
