The Callisto Protocol will feature 10 to 11 enemy types. However, there will be no battles in space.
Studio head and game director Glen Schofield confirmed that there will be 10 to 11 enemy types and no space combat in The Callisto Protocol.

Glen also announced that while there will be sections in space, there will be no combat.
