In addition to the main story, Assassin’s Creed Rogue offers side activities that give players varied and interesting content to play. Finding hidden treasures has always been important part of Assassin’s Creed franchise, because it allows access to special rewards such as weapons, armour or upgrades.
Templar Maps are items in AC Rogue that link to specific locations where you can find rewards – buried treasure, for your exploratory efforts. Each Templar map is a sketch that gives you a hint where to look for hidden treasure, but, if you want to find a treasure you have to equip the Templar Map Tool. When you find location marked on the Templar Map, start digging and you will collect Templar Relics (Templar Artifact). There are 24 Templar Relics in the game, and once you collect all of them you will receive a special reward – Templar 11th century Armour and achievement “Knight of Yore“.
New features include new ship-based weapons such as releasing an oil slick which can then be ignited, Puckle guns, and the ability for enemies to board Morrígan during ship-to-ship combat. The arctic environment also features into naval gameplay and exploration, as certain icebergs can be rammed with an icebreaker.The underwater diving missions featured in Black Flag do not exist in the North Atlantic, as swimming causes the player's health to rapidly deplete due to the frigid water.
