There are 3 missable trophies, "Purist" and "Heartless" and "Humanist". See all 3 of these trophies in the guide for more info. The minimum amount of playthroughs required 4-5 . One playthrough on the hardest difficulty, while completing certain other objectives (see STEP 1), a clean up playthrough,one playthrough acquiring all remaining offline trophies, except for "The Beast".The final 2-3 playthroughs will be dedicated towards this one trophy.
STEP 1: Playthrough on Contractor difficulty + Collectibles + Good Morality Choices
The first thing you will need to do is play through the game on the hardest difficulty, Contractor, while going for all the collectibles, which include radios, neko cat statues and saving hostages. See "The Truth is Right Here", "Touch Not A Cat But A Glove", and "Humanist" respectively in the guide for each of these 3 collectibles. Contractor isn't as hard as it sounds. It's actually quite easy so don't worry too much about it. Also, in this playthrough you will make all positive morality choices. See "Purist" in the guide for more info.
STEP 2: Cleanup Playthrough + Combat/Weapon Trophies
In this step you will go through the game once more (set it on any difficulty you like) and clean up any collectibles that you missed in your first playthrough. You will also get all miscellaneous trophies which include all combat/weapon trophies.
STEP 3: Easy playthrough + Negative Morality Choices
By this step you should have all offline trophies except for "Heartless", "The Pessimist", "The Beast", and "Future Visions". By the end of this step you will have all these trophies except for "The Beast", which will be obtained in the next step. Play through the game on easy and make all negative morality choices. For info on negative morality choices see "Heartless" in the guide.
STEP 4: "The Beast" Trophy
This trophy requires you to get 6,666 cumulative kills in campaign. Each playthrough nets you approximately 1400-1500 kills. By this step you should have about 4000+ kills (as you have completed 3 playthroughs). You will need about 2 more playthroughs before you reach the magic number.
STEP 5: Online trophies
In this final step you will acquire all online trophies. None of them are too difficult and will be obtained naturally as you play online. However, there are 2 quite annoying/time consuming trophies - "Survival of the Fittest", and "King of the Hill". These will take up most of your time while obtaining the online trophies. See both these trophies in the guide for details.

Introduction: The DLC
First make sure you are at patch/update 1.03. This DLC will cost you $9.99 USD for 2 extra chapters and 8 new trophies that you can add to your collection. The team will end up with a new set of tasks, while still having a morality level. Nothing has changed with the two. If you happen to have an old save you will you still have your guns making this game no harder than not having them. You will not hear much from Murray but they will still mention her in the DLC.
Note: The Chapters of Deceit
Make sure you go into chapter select and choose chapter 8 to start the DLC. There have been claims that the trophies will not pop if you have an old save file, so it would be best to copy/back up the save file and then delete it and complete the DLC so you will not have any problems later with any of the trophies.
Step One: The game
Once you go into chapter select put the game on casual (or whatever you feel like playing the last 2 chapters on). Complete the game while paying attention to the hostages in chapter nine and making sure to restart the checkpoint once you get your first Morality trophy. Go for the next one so you don't have to play the chapter over again. There are no missible trophies due to chapter select.
