Developers have told in detail to fans about the new system in the company's official blog.
Players will be able to build their individual items of equipment and upgrades to the bag with bombs and health kits. For crafting you will need circuits, which can be found in chests, get as a reward for completing missions, or receive from allies.
Then players will need resources that can be found all over London. Resources can also be used for other activities apart from crafting. For example, they can be used to strengthen your gang, sabotage wagons and weapons of Templars, get discounts on certain game items in a shop or even to bribe the police with their help.
Apart from crafting developers also have told about the possibility of customizing their characters. Players can change the appearance of characters by selecting various types of clothing and accessories.
