Paradox says you’ll need to pick carefully between them to balance the mobility, firepower, protection, reliability, and cost of your vehicles. The customisable features include armour type, engine, turrets, suspension system, main weapon, and four additional ‘special modules’ of miscellaneous elements. Similar to the ship designer system introduced in the game’s Man the Guns DLC, the new tank designer system will allow you to select a chassis type and outfit it with several different modules, dictating and improving the combat capabilities of your tanks.
Hearts of Iron 4’s upcoming, yet-to-be-named DLC, and its accompanying free 1.11 Barbarossa update, will introduce a tank designer system, letting you customise the chassis, main weapons, engines, and other modules of your armoured units, developer Paradox Interactive revealed in a dev diary earlier today.
