Assassin's Creed Origins

The Walls-of-the-Ruler Citadel is a fortress in the central area of the region, and the story mission "The Walls of the Ruler" will take you here to assassinate Ampelius, so it will unavoidably be added to your map as you progress.

This location has three things to do:

• Kill the captain
• Kill both commanders
• Loot the 6 chests

These are all very straightforward since you've likely done countless of these while working towards the "Old Habits" achievement in the main game. Just use Senu to locate your targets and the chests. The only thing worth mentioning is that one of the two commanders is the large type of enemy that cannot be killed via assassination regardless of your level. Thankfully he is all by himself in a little arena of sorts. I found it easiest to assassinate him (to do decent damage), then immediately use your special attack (having the skill to start battles with full adrenaline is very helpful here), then whip out your best warrior bow and shoot him over and over until your adrenaline builds back up, use your special again, etc. The warrior bow usually stops him in his tracks, giving you another second or two to shoot again.

Once you've completed all of these items, the location will be completed and the achievement will unlock.
