Einhander/Fridge

Fridge Brilliance

Einhander's Excuse Plot actually serves a purpose: to ensure your death. The Einhander missions are suicide missions with no chance of survival. You're supposed to be the same, except for the whole living through the experience part. The train mission was something Selene came up in a pitch to get you killed and collect data on you while they still can. The next two missions come naturally, since by surviving, you entered a base and have to fight your way out. By the time you escape the base, they've worked out a new plan which involves the ultimately inconsequential Climax Boss.
