There's a reason why the Rocksteady and Warner Bros. Suicide Squad game has the words Kill the Justice League as its subtitle. And this new story trailer for the upcoming game explains why. It shows Task Force X's formation (composed of Harley Quinn, Captain Boomerang, Deadshot, and King Shark in the game) and why they have to come after some of Earth's greatest heroes.
Brainiac has possessed the Justice League and is using the superheroes to wreak havoc. We see Superman, The Flash, and Green Lantern in the trailer. Unfortunately, Rocksteady won't reveal when the game will come out yet or what the gameplay will be like. For now, we know it's coming out in 2022 for the PC, Xbox Series X/S, and PS5.
