Hold on a minute. I had just thought, if Richtofen has control of the zombies, would there be any way to stop him. I think there is but I not sure if it will work. If the Gersch device was on the Moon I think there is another purpose for it besides bringing those plates to hold the Golden Rod. Remember how you used the Gersch Device to release Gersch (Zeus Cannon, Porter's X2 Ray Gun, Mustang and Sally, and Matryoshka Dolls required too.) I think that if you throw the Gersch Device under Samantha's body and shoot at it with two Porter's X2 Ray Guns, two Pack-a-Punch Wave Guns (one player uses dual wield while another uses the original, then throw a Quantum Entanglement Device, Richtofen's and Samantha's soul would swap again Just like you saved Gersch. But again I'm not sure it will work.
