You were assigned as the main pilot in Kiryu squad, you need to pilot Kiryu the MechaGodzilla and defeat Godzilla, but in the middle of another battle Kiryu stops responding and you need to reactivate him manually, as soon as you open the hatch and enter it closes behind you and Kiryu gets up by itself, you notice Godzilla got away into the ocean, you also notice that despite all the error warnings it walks by itself, his eyes are red instead of yellow, he is posessed by 1954 Godzilla's soul. Your radio recieves a message from the commandant.

Commandant:"What is going on over there?!"
