Indiana Jones and the Great Circle

There are 44 Adventure books to find - you'll easily see your first through natural play. Then see also Bookworm and then Bookman for the rest.

You'll get this on the way to Archivist - just be sure to pick up all the journal notes you see lying around the place as you play through. This first 50 will be pretty easy and likely come up in natural play.

As with all the collectible-like achievements, buy the book! The guide books from each of the hub areas will highlight where the notes are on your map.

These are all over the place in the Vatican - but they look like croissants! Just pick any one up and eat it.

In the Post Office in the Vatican mission, when you get the camera just take a picture of the person who sold it to you.

Whilst you're there, also buy the Book of Vatican Mysteries to help with When in Rome

As you play through the game, periodically a camera icon will appear in the top-left of the screen - when this happens whip your camera out (Up on the d-pad on a controller) and take a picture. After 50 it'll pop.

This isn't hard, but is worth taking all opportunities for as you play through - to minimise mop-up after completing the story.

There are multiple fly swatters through the game, but you'll see the first whilst rescuing the nun in the tower. Hit any enemy to pop this.

Open your map, go to Travels and pick another location - you have to have been to at least two before this can be done; you can do it from when you reach the Vatican.

There are multiple Starfruit around Sukothai - just pick one up and then eat it.

As with many of the other collectible-like achievements - buy the book! In this case its the Book of Vatican Mysteries which can be bought from Ernesto in the Vatican post office (where you'll also need to be for Ecco!)

There are three underground boxing clubs - one in each of the main hub areas. At each one you must defeat three opponents, the third is the local champion. Beat the champion in each to unlock this achievement!

This is in a side quest in Gizeh which you can start by talking to Gina in Nawal's tent. There are four frequencies to collect.

This is an Objective, rather than All-the-things, as the quest gives you a map with four areas, so its basically an Objective to complete the quest rather than collectible-like.

This is easy if you buy the artifact guide books in the shops in the hub areas (Vatican City, Gizeh and Sukhothai) - once bought, all the artifacts will be highlighted on your map so they are super easy to find.

No checklist needed as the game keeps track for you and shows you where they all are.

This would be hard - except for the guide books you can (and should!) buy in the three hub areas. Buy those and the locations will show up on your map. Make sure to pick them up as you play through naturally, and just fast-travel back later for any you've missed. You should pick up Field Survey for the first 50, and then this one when you've got all 100.
