Epic’s E3 plans for Fortnite include a $3 million prize game of Fortnite for charity.

Fortnite Pro-AM will pair up fifty popular streamers with fifty celebrities in the charity match. Five of the partnerships have been announced so far; including a team-up of Ninja and music producer Marshmello, and pairing YouTube personality Markiplier with comedian Joel McHale. The 3,000 tickets will be available for purchase for $10 via an email link sent to players in the Los Angeles area.

E3 plans for Fortnite also include an exclusive “Party Royale” at the event, with hopeful attendees able to potentially chance a ticket off Epic’s E3 booth.

The victorious pairing will be awarded $3 million to donate to a charity of their choice. Epic stress that the hefty prize pool for Pro-AM is not a part of their previously announced $100 million esports prize pot for Fortnite.

Personalities have helped catapult Fortnite into a worldwide phenomenon, and it’s not surprising that streamer-celebrity showdowns factor big in Epic’s E3 plans. SuperData reckon the Ninja-Drake stream back in March helped Fortnite bring in $223 million that month.

Fortnite Pro-AM will be streamed live at 11:30pm BST on June 12th.
