Aliens: Fireteam Elite 2 Best Class
There is no universal best class: choose by squad need, difficulty, weapons, and the job your team is missing.
There is no verified universal best class in Aliens: Fireteam Elite 2. For a first clear, use the class whose weapons and abilities let you perform one reliable squad job; in co-op, filling missing control, sustain, or damage is stronger than copying a launch-day tier list.
