Having rescued Naomi and an injured Raiden, Snake and Otacon return to safety. According to Raiden, a woman called Big Mama has the corpse of Big Boss in eastern Europe. Liquid is seeking the corpse, it seems, so it's quite clear that this will be Snake's next destination. The group comes up with a plan to get him into the PMC-patrolled city where Big Mama resides, while Naomi appears to be hiding something...

Snake and EVA head for the pyx.
