Suicide Squad: Kill the Justice League is an action-adventure game[2] set in an open world based in Metropolis. Players control the Suicide Squad, which features a total of eight playable characters, including the four initial members, Deadshot, Harley Quinn, Captain Boomerang, and King Shark,[3] and the post-launch additions of the Joker,[4] Mrs. Freeze,[5] Lawless,[6] and Deathstroke.[7] While it can be played solo, the game features a four-player cooperative multiplayer mode. When played solo, players can switch between characters at will, while the other characters are controlled by the AI.[8][9]
Each character has access to three weapon classes, with each class being shared by multiple characters. Each character has a unique melee combat style and traversal method, such as Harley Quinn who uses a bludgeon and travels using Batman's grapple gun. A skill tree progression system is included, allowing players to re-spec into different skills at any point throughout the game for different build experimentation.[10] Post-launch content was released in the form of "seasons", with frequent free content updates featuring new locations, activities and playable characters.[11]
