The Ceph Mastermind is an incredibly powerful Ceph unit encountered near the end of Crysis 3 . A large opponent of large size and physical Strength, the Mastermind is a difficult enemy to overcome, so much so it is only fought once in the game. A dead Ceph Mastermind which is preserved for research is first seen in the advanced nano tech research department of the skinning labs, and fought later in the level 'Only Human'.
