The Cognitive Disruptor is an 
Illuminate structure that affects a 
Helldiver's ability to call in Stratagems. While it does not completely block stratagem use in the way an 
Automaton Stratagem Jammer does, it can still produce unwanted effects.
Appearance
A Cognitive Disruptor appears to project a massive pastel-colored energy field across much of the map, often visible as Helldivers first arrive into a mission. The two-pronged tower measures roughly a hundred meters in height. It vaguely resembles a sword in shape.
In a disturbing encroachment on providence, Cognitive Disruptors are generally connected to humankind's energy grid, corrupting one's very desires in service of tyranny.
Tactics
When approaching within 200 meters of a Cognitive Disruptor, one begins to notice their Stratagem display becomes difficult to read, and that input codes are frequently replaced every three (3) seconds. The input codes may even resemble those used by other stratagems. Defeating this mental attack requires concentrating on the official MoD-standard symbology for Stratagems, and inputting the given code before it is cycled. Failure to properly input a code may result in a different stratagem being called.
Even closer to the Cognitive Disruptor, one may notice additional sensory disturbances. In the ten-meter radius of the tower, the Helldiver needs to locate four energy conversion panels attached to colonial power equipment.
Stratagems that deliver heavy fire over a moderate area are effective against a Cognitive Disruptor:
