A Datamass is a Corpus data storage device. They are affected by physics and behave like other loot drops. It is possible to blast a Datamass away with explosive weapons such as the Ogris. When a datamass is picked up, the carrier will automatically switch to their secondary weapon. If they switch to their primary weapon or melee weapon, they will drop the datamass. Pistols and quick melee attacks can always be used with datamasses in hand, regardless of whether or not they are two-handed/akimbo.
