Assassin's Creed Valhalla on PC

To get Thor’s Hammer, you will need to finish the main game and have the full set of Thor’s Armor.

3 of the Thor’s Armor pieces can be obtained by defeating the 3 Sisters of Lerion.

Thor’s Helmet is found in East Anglia Cave.

Thor’s Cape is a reward given to you by Hytham if you defeat all of the members of the Order of the Ancients.

These 5 pieces make up the full Thor’s Armor set.

Once you’ve completed the main story, put on all 5 pieces of armor from the Thor’s Armor set and head to the north of Norway, where you will be able to take Thor’s Hammer. It will only appear if the main game is complete and you are wearing the full armor set.

During the modern-day sections, you can read an email between the protagonist Layla and her brother discussing the COVID-19 pandemic, among other small references to it due to the modern-day sections being set at that time.

If you complete all ten of the Animus Anomaly puzzles and then complete the final mission of the main game, you will unlock a secret ending.

To unlock Asgard, you will need to complete the quest “A Wise Friend,” and then do the quest “In Dreams” up to the point when you bring the plants to Valka to make the potion. If you drink the option, you will be taken to Asgard and unlock it as a location.

In Essex, you can find a small musical group that includes Keith Flint, from the real-world band The Prodigy (which comes from Essex). The group is having trouble with the bishop, which leads to a fight that includes “Smack my bishop!” among the words of encouragement shouted to you. This is a reference to one of The Prodigy’s songs.

You can also find a page of lyrics nearby for a song called “Charly,” another reference to one of their songs.

In addition, when you talk to Keith again, it will unlock a World Event also called “The Prodigy.”

In a building east of Ledcestre, there is a bonfire with a sword stuck into it. You can meditate by the bonfire to restore energy. This is a reference to the bonfires in Dark Souls.

Near Glowescestre, you can find a small village that contains moss-covered homes and resembles Hobbiton from The Hobbit and Lord of the Rings. One of the homes includes a note with a ring on top of it, and the note says, “One of the little folk asked me to make the door smaller, as he wants to keep unruly houseguests from his house. After the nonsense with the druid last fall, I can see his point.” This further suggests that this is intended to be a reference to The Hobbit, with the druid being the wizard Gandalf and the villager who wants to avoid unruly houseguests being Bilbo.

In Asgard, while talking to Ivaldi, he will eventually start listing several people’s names. These names include Gandalf, as well as some of the dwarfs from The Hobbit.

Additionally, some people feel the Lord of Norsexe World Event, in which a man asks you to retrieve a “precious” ring lost under dubious circumstances, is intended to be a reference to Gollum, although the connection here is more tenuous.

There is a cell in the Dunwic area where you will find a group of chickens. If you attack one, they will all turn and attack you as a group, a reference to what happens in the Legend of Zelda series if you attack a Cucco too many times.

The same area contains a note that rambles on about spider legs clicking and telling the writer things related to an unknown world. Since the area is Dunwic, this is most likely a reference to H.P. Lovecraft’s story The Dunwich Horror.

There is a quest to collect the pages of a book, which turns out to be called Fantastic Fish and Where to Find Them, a reference to Fantastic Beasts and Where to Find Them from the Harry Potter series.

In Lunden, you can also find a building guarded by a snake, and inside there is a list of items that match up with Voldemort’s Horcruxes.

There is a hidden side quest in Northwic that lets you unlock a cat for your ship. Talk to the white cat in town, and then talk to the kid nearby after the cat runs away. This will begin the Freyja’s Friend side quest, in which you have to catch the cat. Once you successfully catch the cat, it will appear on your ship from then on.

You unlock new abilities by finding Books of Knowledge. A book will let you unlock one new ability. Finding a second book for the same ability will upgrade it to a more powerful version.

To get Excalibur, you will need to get all 8 Treasures of Britain as well as 3 Tablets from the Zealots named Woden, Heike, and Hrothgar.

The Treasures of Britain are marked as Mysteries and involve platforming sequences in order to reach them.

The three Zealots patrol the roads in specific areas.

Once you have all 11 of these Tablets, take them to Myrddin’s Cave in Hamtunscire and use them at the stone circle to make Excalibur appear for you to take.

Near Glowescestre, at the Crossroads, there are three guards who walk past whom you can fight to loot Titanium, Nickle, and Tungsten from after their defeat. However, they will respawn if you re-load the area. This means you can keep saving at this spot and loading your save to fight them over and over and get unlimited Titanium, Nickle, and Tungsten.

Use your raven to get a view of the area, as well as a guide leading you to your goal.

Odin’s Sight also provides you with a special look at the area to help you find targets, items, and more.

To heal, you will need to use rations. Gather berries and mushrooms to make rations or buy rations from vendors.  

There are many skills you can unlock, and you can re-spec at any time if you decide you dislike the skills you chose.

Some early skills to consider include Auto-Loot, which lets you automatically collect loot instead of picking it up manually, and Breakfall, which minimizes fall damage.

You’ll also want to upgrade your rations pouch as soon as possible so that you can carry more rations, as well as your quiver to let you carry more arrows.

Try not to worry too much about silver early on in the game, as it will become more plentiful by the time you really need to buy things. However, selling unneeded runes and gear and playing the gambling mini-games are two ways to earn more silver quickly.

Gather arrows whenever you can, because they are in somewhat short supply. You’ll want to gather them from buildings as well as from defeated enemies.

If you’re near water, you can call your crew for help during battles, and they will fire upon your enemies.

There are a lot of things you won’t unlock until you’re a significant way through the main story, such as the Leap of Faith and Assassinations. Therefore, you might consider sticking with the main story through the first act before exploring the world and doing side content, to have all the major game mechanics available to you as you do so.
