Two plotholes in the fifth act...SPOILERS
In Act 5, first Akiba falls into the ocean then he shows up during the Screaming Mantis battle. How did he get out of the ocean?
Secondly, how did Raiden get through those doors in that tunnel to GW? How did he get on the ship, past the guards, down the elevator and through the control room without any arms? These are never explained.
