Modular armor

Modular armor connects the basic concept of Armor with the later stages of wearable technology represented by Power armor and Power armor MK2.

Modular armor is listed alongside related concepts such as Armor, Power armor, Power armor MK2, Resistances, and Spidertron. These relations reflect its role in the game's equipment and defense systems: it serves as the modular, upgradeable armor type that bridges early personal protection and the more advanced, high-capacity Power armor variants. Modular armor is associated with managing resistances and with equipment that augments mobility and survivability.
