Class System Overview
Aliens: Fireteam Elite 2 features six base classes, each with unique abilities, weapon proficiencies, and team roles. The biggest addition in the sequel is the Expert Class — a fully customizable class that lets you mix and match primary and secondary skills from any base class, creating truly unique playstyles.
Each class has:
- Primary Ability: A class-defining skill with a moderate cooldown (15-30 seconds)
- Secondary Ability: A supportive or utility skill with a longer cooldown
- Ultimate: A powerful team-wide ability that charges through combat
- Passive Trait: A permanent bonus that defines the class role
- Weapon Proficiency: Bonus damage and handling with specific weapon types

Expert Class (NEW in Fireteam Elite 2)
The Expert Class is the biggest innovation in the sequel. This fully customizable class allows you to select one primary ability and one secondary ability from any base class, creating unique hybrid playstyles that were impossible in the first game.
How It Works
- Select Primary Ability: Choose from any base class's primary ability (Gunner's Overclock, Demolisher's Micro Missiles, etc.)
