Armored Warfare will bring a "Retrofit System" to their game. We will be able to install things like Improved Spall Liners, Internal Hull Reinforcements, Reinforced Ammorack and Reinforced Engine housing.
One of the things that I find interesting is that they will be giving 5 types of Retrofit Slots for each type of system (Firepower, Armor, Mobility, Technology and Universal) and they made a pop-up panel that shoes how each Retrofit System will affect the vehicle statistically.
I'm aware that WoT also has a type of pop-up % info on their Equipments but would love AW to add more detailed info. For example...if there are tanks that are more prone to being ammoracked, imagine if they could show the data of the vehicle so that, once the player passes the mouse over a Retrofit System a +X or -Y number would be given to show how the vehicle becomes affected.
