But wait — your fellow heroes may be villainous HYDRA operatives in your midst! Use social deduction to determine who is a secret HYDRA agent and who is truly loyal to S.H.I.E.L.D. If you succeed, you and your fellow S.H.I.E.L.D. heroes will retrieve the Cosmic Cube from the Red Skull and save the city! If the city is destroyed, HYDRA wins.
