The Possessed Trooper is a Collector unit encountered in Mass Effect 3. It is an enhanced variant of the Collector Trooper.



The Possessed Trooper is armed with a Collector SMG, the same as a Collector Trooper. It can create a Collector Web to snare enemies but lacks the grenades of its regular counterpart.


It has moderate health (50% more than its normal counterpart) and gains a layer of barriers. It will often take cover during combat and can avoid attacks by rolling. Like other Mass Effect 3 enemies, it can be staggered by gunfire or powers if unprotected by barriers, and headshots will inflict 40% additional damage to it.


  • For the most part, dealing with this enemy is no different from a regular Collector Trooper. The only difference comes in using webs rather than grenades, which actually makes them somewhat less of a threat, as they're unable to flush you from cover in that way.
  • The Collectors always strike and deal damage with their melee blades twice; a batarian's Blade Armor will cause the Trooper to stagger back after dealing their first blow, thus preventing them from dealing the full damage of both strikes. This allows a batarian a good close quarters advantage against the Collectors over other races.
  • Collector SMGs' weapon tracers are light gray, making them very hard to see. It's very possible to be taking fire from one without noticing, which can turn a casual hop from cover to cover into a very bad idea.
  • Possessed Trooper remains immobile while creating the web, unable to dodge or retaliate. The web itself can be safely ignored unless it's directly in your way.
