Like past games, you can buy new mounts in Assassin’s Creed Mirage. To do this, look on your map for an NPC with the horse head symbol. There are several of these stable NPC traders throughout ...

you’ll automatically get the quest “Mount: Doran’s Favor.” Simply head to the stables, talk to the stablemaster, then find Doran at the Cathedral. Boom, you’ve got a horse now!

Then, stealthily crouch-walk to get behind a horse and press A to mount up. In most cases, the horse will buck to throw you off. You have to press the L button repeatedly to get it to calm down.
