To find out how the XCOM 2: War of the Chosen expansion's new Ability Point system affects soldier abilities and builds, check out our War of the Chosen Ability Point page. Here, you'll find full reference guides for the skill tree of each soldier class, in addition to pointers on particularly powerful ability combinations, and how their canny tactical use can turn the tide of battle. In all cases, advance knowledge of each soldier's skill tree can offer a distinct advantage in understanding how earlier abilities might interact with later ones. Meanwhile, the Psi Operative offers a more randomised approach to promotion.
Each of the four standard soldier classes has two distinct upgrade paths that offer unique and mutually exclusive builds, or that can be customised by cherry-picking abilities from each specialisation.
The Soldier Abilities in XCOM 2 represent your squad's most valuable weapons in the fight against the aliens.
