Alpha Protocol

Acheivement translation : Fight Leland as the final boss (instead of Westridge).

There are 3 requirements to trigger this :

- Void the other 2 endings, which can be done by making sure Leland doesnt "trust" you (meaning : below +4 like). If Leland doesnt offer you a job at the beginning of the final mission, you're good. If he does, refuse/punch him.

- During the Moscow mission "Intercept Surkov at US Embassy", you MUST bluff the guards at the entrance and make them you allies. Which means : do NOT avoid them by using the ladder to get around them, do NOT shoot any guards even by mistake once the firefight begins, do NOT go outside using the door on the second floor or you'll be considered an intruder even if you made them your allies (but on your way back to save Surkov, you can go out using that exit, the sniper will be there if you bought the intel).
If you fail any of the above, you will see it in a RED sentence in your debreifing at the end of the mission. And at some point Leland will tell you that you can never hope to reconcile with Alpha Protocol, that you are alll alone.

- Lastly, IF you spared Shaheed during Saudi Arabia (if you executed him, you're good), you can meet up with him again before the final mission. He will ask if you're willing to betray America. Your answer MUST be no.

I obtained this achievement, without ever officially siding with Alpha Protocol.

I was also trying to go for the 'Judge, Jury and Executioner' achievement, so I executed everyone that I had the chance to during the game.

I also was going for the 'Youth Trumps Experience' and the 'Never Trust A Sociopath' achievements.

So by the time I reached the end game mission, I was hated by Heck, and had executed everyone, including Marburg.

During the final interrogation room scene with Leland, he never offered me a job. At the end of the final mission, Leland was the boss, and again, I executed him as soon as I had the chance.

I'm sure there are many other ways to obtain the achievement, but it's how I did it
