*Spoiler*(in the video and guide) Check the video for all endings
If you want to get this achievement very easely and fast pick the choice A or B because these missions are quite fast BUT if you are still trying to get other achievements and if you are enjoying the game and you don´t want to rush then you should choose the option C/Deathwish (the best ending in my opinion). Once you complete the mission, you will see the credits roll and the achievement will pop up too.
*Once again if you need other achievements make sure you create 2 save files, 1 before this mission and another when you complete this mission just to make sure that you get all the achievements in the game.
Don´t forget that if you want you can play all the ending choices by pressing START then GAME and then Replay Mission option.
Hope this guide and video were helpful if you have any questions and/or sugestions leave in the comments.
