Sequence 1: Awaken
Kill 5 Bluecoats at the church while remaining undetected.
Make sure you do not use any weapons to kill the guards. When you jump off the tree, run past your mother into the hay cart to the right. Jump in and kill the first guard using Next run all the way to the left of the cemetery and kill the guard right next to the broken wall. There will be two people in front of you now. Wait until the bluecoat patrolling goes behind the building and kill him. To go to the left corner of the building and whistle to get the bluecoat who is crouching to walk over to you. Kill him. Go back to the haycart and kill the guy by the bushes on the other side of the wall. If you kill the guy by the bushes, make sure the patrolling bluecoat is on the other side of the building. Kill the one standing then wait for the patrolling one to come back around and turn his back to you. Walk up and kill him. The challenge should be complete and there will be no timer. You are now free to kill everyone else and continue the sequence without stealth.
Prevent any Bluecoat reinforcements from reaching Concord.
When you are manning the cannon, make sure you do not worry about the people shooting at you. Only worry about those on the main road. Just lead your shots a little bit (anticipate a second delay before the shot hits) and you should be able to complete this no problem. After you hit the first shot, enemies will be in fields and on the roof of the building to the east. You have time to kill the bluecoats on the rooftop before the next wave comes. If you time your shots correctly you can also take out the men on the ground while taking out a wave of enemies. You do not need to worry about the foot soldiers shooting at you however.
Do not permit any Bluecoat runners to light a fuse
The runners carry torches and are marked with larger circles on your minimap. You don't have to worry about the other bluecoats. There's only about 6 that may attack you. Just run at the runners with your Tomahawk or if they get too far away use your bow and arrow.
Sequence 2: Warn the Village
Sequence 3: Sky World Journey
Don't touch any rocks during slides.
Tad tricky because it's hard to see anything. You have to slide down a hill 3 times and the notification about the objective will appear before you go down each. None of them are too hard to slide down. Just steer with the right stick and you should be able to do it.
Kill the Elk without alerting it.
Press and cloak. Then walk up to the elk and hit .
Sequence 4: One-Man Wolf Pack
Kill 2 bluecoats with a single arrow
Walk around until you find two bluecoats standing side by side. Hold down then fire to make the shot more powerful. Hopefully you will kill them both. Easiest spot I found was as soon as the challenge pops. There will be two bluecoats running up a hill. Follow them until they reach the top. They will be walking single file and you have a perfect opportunity to kill them both.
Kill the runner by calling the Wolf Pack
Hit as soon as the challenge appears and the enemy is highlighted to kill him with your wolves.
Sequence 5: Path of Revenge
Use no stalking bushes during the eavesdrop.
Do not even touch the shrubs and plants in the area. Instead jump into the pile of hay. When the soldiers move, hit to become invisible and jump out of the hay and move to the haycart. Stay there until they move and then turn invisible again. This time go jump into the well. If done correctly you should have successfully eavesdropped on the soldiers by the time you reach the well.
Sequence 6: Justice Served
Free the bear without killing or alerting the guards.
After you chase Benedict Arnold, there will be a bear in a cage. Use your Wolf Cloak and and walk over to the cage. Hold to open the cage and then leave the circle.
Stay undetected in the fort.
Use your Wolf Cloak and you can basically walk straight up to Benedict Arnold and stab him. Use the bushes to regain health if it gets low. You don't technically have to kill any of the bluecoats.
The best way to do these challenges is to ride a horse between the two towns in the middle. There is a set place for a wolf attack and several starving citizens spawns. Convoys spawn less commonly but they do appear. You can always reload the area if you don't find a second convoy after a while.
Attack 5 Convoys
Convoys are randomly spawning. You can find them by the moving red square. You will have to kill about 10 bluecoats and then open the cages for it to count. The most common locations for them to spawn are in towns.
Help 5 Starving Civillians
There will be an indicator on the map. You just need to walk up to the person and press .
Attack 5 Packs of Wolves
You can't just kill any wolves. There will be an indicator to show you where the wolves are attacking the citizen. There will be 3 wolves each time. There is however a rare chance that you will also have to protect the civilian from bluecoats.
Find the Lucid Memory Artifact
There are three artifacts in total.
In a burnt out tavern on your way to the first missions.
On the top of fort you are at during Mission 5.
When you finish the game you will be in a U shaped town. It is along the river to the right of this town (top of the map, mid right).
