If you're getting stuck into Assassin's Creed Unity this weekend then you'll likely stumble across a collection of truly maddening mysteries in the form of Nostradamus Enigmas. These obscure riddles are littered all over Paris, and require you to interpret the sort of clumsily structured prose that would make Dan Brown blush.
We're working our way through the main storyline of Unity in a seperate walkthrough article, but we thought it might be handy to put together a quick, separate guide for you that breaks down every one of these mindbending puzzles, and shows you how to pick your way through the obscurity.
Once you've tracked down all of the Enigmas outlined in the links below, head back to this page for a guide on how to solve the puzzles and loot your lovely armour reward.

The Cella Constellation
Once you've grabbed every last one of these puzzles, you'll be able to open up the cage that contains your reward. Make your way towards the underground part of the mansion containing the Cafe Theatre, then solve a trio of puzzles to open up the cage and get your hands on that delicious Thomas de Carneillon armour.
When you have four fragments you'll be able to tinker with the Cella Constellation by fiddling with the pedestal in the middle. The puzzle here isn't too tricky, and you just need to line up the pillar symbols with the corresponding symbol on the ground. Use the walls to find these pairs and get them nicely lined up.
As soon as you're done, you'll see a new opening appear in the wall that's just above the puzzle room. Clamber up, then make use of the pillar handholds to get inside this opening. Finally, interact with the lever to take away the first protective section of the cage.
The Cella Astri
When you've gathered at least 10 bits of the Enigma collection, you'll be able to unlock the Cella Astri. To do this, interact with the central pedestal, then enter the room that opens up. Next, you need to play with the collection of switches so that the planets line up with their equivalents on the ground. It's a fairly simple observation puzzle, but we'll give you a quick walkthrough.
First, press the left-most switch three times, then the middle switch once, then the final switch three times. When you're finished, a new opening will appear. Go to it, then use the lever to remove another bit of the cage's protection.
The Cella Vaporis
When you've collected all 18 of the Nostradamus Enigmas you'll be able to unlock Cella Vaporis. Once again, go to the central pedestal, then leap from stone to stone to reach the new opening. Just watch out for the scalding steam that fires at you as you go. When you pull the final lever, you'll be able to grab your lovely loot. Congratulations!
