Many gamers have been struggling with Assassin's Creed Odyssey seeing as it is a rather difficult entry in the series so here are some tips that may help you if you're finding it to be too hard.
Lurk in the shadows
The most crucial aspect when it comes to infiltrating enemy strongholds is to be sneaky. Sure, you can rush in head-first but you'll likely alert all the guards and have a steep uphill battle to fight as a result. Instead, tap the crouch button to enter sneaking mode then carefully stick to bushes and hug walls as you slowly traverse the environment. Whenever you see a guard, you can approach him from behind and the amount of damage that you'll do if you decide to assassinate him will display on his health meter. If you can instantly kill him then go ahead. If not, judge whether it'll be worth a short fight to finish off his remaining HP. I personally didn't bother hiding the bodies afterwards as I found that it made me vulnerable to be spotted by another foe but if you can do so easily then it might be a good idea so you can avoid alerting the rest of the guards.
Learn to dodge
Combat in Assassin's Creed Odyssey can be hard but the key to victory is dodging. Considering your character can endlessly dodge by repeatedly tapping the dodge button, it's very easy to avoid incoming attacks. A solid tactic is to dodge around enemies and attack them whenever they're vulnerable which will usually be right after they strike. Of course, if you're facing more than one opponent then this can get tricky so just be patient, keep dodging, and hopefully you can eventually deplete their health before more enemies come.
Watch for brazier lighters
When infiltrating enemy territory, an alerted guard might run to their compound's brazier (a giant torch) and light it which is a visual signal for all the enemies in the area to come to the compound and gang up on you. Needless to say, this is bad news. Therefore, if you happen to alert the guards and see one running to the brazier then quickly run towards him and end his life to prevent him from doing so. Next, stand near the brazier and dispatch any remaining guards that are likely following you at this point. Thankfully, the guards take a while to light the brazier so you'll always have a decent window of time before it's too late.
Know when to fold 'em
Of course, there will be times when you alert the guards and you let one slip by who then lights the brazier. Also, you may find yourself facing enemies that are at much higher levels than you which is indicated by a red skull. In either case, it's probably a good idea to run instead of trying to fight your way through. The best way to retreat is to dodge away from nearby enemies then run in the opposite direction. As you run, hold down on the D-pad to call your horse. Keep running and holding the button then your character will automatically mount the horse and you can then freely escape to a much safer location. Or, just reload a recent save file.
Use abilities, especially Second Wind
Many Assassin's Creed Odyssey players don't use abilities enough but they're extremely useful and most of them recharge quite fast, too. You can purchase abilities with ability points in the Abilities menu upon pausing the game. There, you'll find many passive boosts and useful skills such as the ability to charge an attack, reveal surrounding secrets, and inflict poison when attacking an enemy. However, I found the most useful skill to be Second Wind which is located in the Warrior section. With that, you can restore 25% of your health whenever you use it and it doesn't take long to be able to use it again so it's incredibly handy for surviving long battles.
Grind, equip, and upgrade
Assassin's Creed Odyssey is the most RPG-heavy entry in the series so far. Because of that, level grinding and optimizing equipment are key to turning the odds in your favour. The best way to grind is to explore your map and visit every question mark as well as activate each Synchronize Location which unlocks Fast Travel points. This will allow you to see what objectives are available as well as quickly travel long distances. Next, visit Message Boards and complete optional quests which rewards a great deal of experience.
When it comes to equipment, equip all of the highest level gear that you can then visit a blacksmith to Upgrade and Engrave equipment pieces as much as you can. Don't worry about wasting materials and money as you can acquire more rather easily.
If all else fails, change the options
If you're still struggling with how hard Assassin's Creed Odyssey is, there's no shame in lowering the difficulty. To do so, pause the game, tap left on the D-pad to enter the main menu, then select Options. Head over to the Gameplay heading and change the Difficulty option to Easy or whatever you wish. Next, choose an Aim Assist level if you're having difficulty with your bow and arrow shots. For the record, Full is the easiest setting. Finally, if you're having trouble with getting lost in the world, choose Guided for the Game Mode option.
