Had David Jaffe (director of the first game) made this game, it would have been very different. The idea he had was that Zeus would have been defeated in the first few minutes of the game. In the power vacuum that would follow the gods of other mythologies would have appeared to fill the space left by the loss of Zeus. Kratos would have used Thor's hammer as a weapon. The ending would have shown the Three Wise Men (Kings) following a star.
The developers were very against Poseidon having tentacles during his battle since it would have drawn comparison to the Hydra battle of the first game, so crab legs were used instead.

Originally exclusive to Sony Computer Entertainment's PlayStation 3 (PS3) but was later ported to the PlayStation 4 (PS4).
