That's awesome, congratulations! While the event officially starts on May 1st, it's still pretty cool to see you've taken on and beaten the challenge, especially on Trial by Fire.
Any particular strategy you used for the final battle?

Not much to say for a 'strategy' - a lot of evasive maneuver and taking cover, plus a small portion of luck, perhaps? ;) I picked out the Scouts first cuz their speed and bullet spraying make their attacks harder to evade than those of the other bigger enemies. And I tried to minimize the flank attacks by enemies - in Trial by Fire difficulty, those are pretty lethal. Using the front-shield saved my life so many times, of course.
