I made an 100% achievement walkthrough.
This game takes 3 playthroughs to complete.
You can get all the achievements in under 2 hours.
For the first playthrough @1:05 you'll get the achievements:
-Anarchy Man
-Doctor
-Stolen Car
-Playing House
-Charmer
For the second playthrough @35:35 you'll get the achievements:
-Conformist
-Peeping Tom
-Bucksickle
-Insomniac
-Terminated
For the third playthrough @1:06:15 you'll get the achievement:
-Getaway
For this specific achievement you need to make it down to the lower levels, get the gun and shoot an Android until it dies.
Check out my video to see how to get to the lower levels, go through the lower levels, where the gun is and how to kill the android @50:45
*note* this achievement is buggy after recent updates. You might have to do it a few times to get it to pop. If it doesn't pop you can exit the game and load last checkpoint to try again. Check the comments for more info
