Weapon modification

Weapon modifications, more often known simply as weapon mods for short, are hot-swappable attachments and modules for the Doom marine's weapons in Doom (2016). Any weapon modification for a weapon which the marine currently possesses can be obtained by locating combat support drones  - also referred to as field drones - which are small hovering robots which hold a touch screen allowing selection of the modification to unlock. Most weapons in the game have two modifications available, usually adding attributes such as an area damage effect, greater accuracy, higher rate of fire, or penetrating projectiles that can harm multiple targets. The effectiveness of many weapon modifications can be increased through use of weapon upgrades.

Only one modification can be active on a weapon at a time, but after acquiring both of them the modifications can be swapped out at will.
