BioShock Remastered

If you are like me and forgot a type of splicer, Big Daddy or machine when you arrive at the final level you can always go back. I didn't think about that and replayed the whole thing...

The types you need are:

Thuggish Splicer
Leadhead Splicer
Houdini Splicer
Nitro Splicer

Rose Big Daddy
Bouncer Big Daddy
Little Sister

For all of these there is an additional achievement so these are easy to track.

Then the ones most overlooked are the machines:

Security Bot
Turret
Camera

For this achievement there is a sneaky trick. If you play through the game on easy mode and turn Vita-Chambers off, save regularly to prevent replaying large portions in case you would die.

Then when you reach the final level you set the difficulty to hard and beat Atlas. The achievement will unlock between defeating him and the minor cutscene after beating him.

This achievement is for picking up all 122 audio diaries hidden throughout the game. I made a video guide going through showing the locations of all of these below.

This one is for rescuing the little sister in under 3 minutes on "The I in Team" challenge map. This challenge map is pretty easy to get done though as long as you follow this video guide I made down below. You probably won't have any issues with it after you watch it through once or twice as it's a pretty simple one to get through once you know the core concepts of the puzzle.
