Ok, done. End of turn 19. Start of turn 20.

Predator landed and snake is his victim. He will go toward him with speed of 2 spaces per turn and kill him. Only way for him to be saved is to get to the place with the chopper icon. ''Get to the chopper snake''.
Or you can go to extraction point meant for viral victims. In any way all I can see is that you are very lucky and you can escape the city with no problems. But, no bonus for finishing the main quest.

Snake to move next.
