Parkour is upgraded with tree climbing and new animations

Stealth is upgraded by having physical stealth skills such as hiding in mud, snow, crouching in bushes, hiding in bales of hay, etc. Players can now also hide in crowds of civilians if their outfit/armour is appropriate otherwise it can attract attention.

Note! Co-Op will be included

Up to 4 player drop in drop out co-op like Ghost Recon wildlands.

Assassin's Creed Ragnarok is also going to feature a reputation system, which will make quests and missions available in certain kingdoms only once a certain level of reputation has been reached.

Players now have a reputation system based on quests completed for people in cities, the town officials, clothing worn, crimes committed, etc. Some quests and story missions can only be completed after reaching a certain reputation with kingdoms.

Assassin's Creed Ragnarok is also going to do away with level locked regions, with a new progression system.
Levelling is overhauled to allow players to improve skill sets to gain experience, like in Skyrim. As a result, level locking regions and content is gone.
Some skills are unlocked by reaching a high enough skillset level, some must be bought with skill points, and others are unlocked through game/ story progression.

The Assassin's Creed Ragnarok map is also said to be massive, featuring almost all of Northern Europe as well as big cities like York, London, Paris, and Kiev.
The map is massive. Like all of northern Europe. My source mentioned big cities being York, London, Paris, and Kiev. Every kingdom was meant to be really unique.
