How to get endings and their dialogue (Spoilers)

Warning! This page contains unmarked spoilers! If you want to have all the endings come as a suprise, go back now.

I warned you.

(All endings with A.S.A.S speaking (aside from escape and truth) begin with this dialogue:

A.S.A.S: And here we are again. Did you miss me? How many countless lives have you torn apart this time? You know why you're here, and it's always nice for you and I to have these little chats.

In order to get this page out there quicker, this dialogue will be omitted from all endings.

The Bad Ending (Warhead Detonation)
How to get: Wait until the warhead event. Do not disarm the warhead. Do not use the rocket to escape. Simply wait until the detonation.

A.S.A.S: Oh dear. That was very unfortunate. I wonder why this someone or some group would sabotage the facility in such a destructive way? Think about the innocent people there. Who knew a power plant would be holding thermonuclear warheads? Oh well, you should have done a better job at stoping it, but everyone makes mistakes right? Thank you for coming to my DED talk and i'll see you later.

Note: DED talk is a reference to TED talks, a video presenting an idea in a short time frame, delivered on a stage by a single person.

The Not So Smart Ending
How to get: Cause meltdown. Do not escape via rocket. Do not go to subbase 6B. Do not enter the emergency bunker.

A.S.A.S: Wow. Just, wow. For an experienced person such as yourself, if I can say that, you have impressed me in the wrong way. Not only were you unable, it appears you didn't even try. You failed to stop the reactor core meltdown and failed to do something as easy as entering the emergency bunker. I am intrigued by your actions and I wonder what you'll do next time. For now, I'll see you later.
