Enragers are red bulbous jellyfish-like creatures, whom act as "middle management" in the Alien horde according to the lore in Earthfall, increasing the strength of other Alien classes by their mere presence. They are encountered on every level of the Campaign and Invasion, though their appearance is random so their isn't any spot to farm them. You'll know the arrival of Enrager by their fog horn call, AI teammates noting its presence, and a red radar that emanates from their location (which can be seen behind solid objects such as walls). Enragers are often found in the rear of Alien horde attacks or hiding of in corner, as they not overtly aggressive themselves. The only times they themselves will attack is if they are all by themselves, in which case they'll make a suicide charge towards you and your teammates and explode (this tends to only really happen in Invasion rather than Campaign). Unlike, Drones (Light Drone, Heavy Drones, Spitter Drones) Sappers, Whiplashes, Threshers, Beasts and Blackouts, the AI tend to not steal Enragers kills from you that often.
