As if battling the corrupted forces of the Justice League wasn’t stressful enough, players now have to worry about Edward Nigma, an escaped Arkham Asylum inmate who has managed to hack the bombs of Task Force X and is threatening them with an explosive migraine (not from his incessant talking) unless they solve his riddles all across Suicide Squad: Kill the Justice League’s Metropolis.
