The game uses a third-person perspective. Players guide Gabe through linear missions with optional exploration, completing objectives such as eliminating targets, rescuing civilians, securing evidence, and reaching extraction points.

Gabe can run, crouch, climb, use weapons, interact with objects, and employ equipment such as night vision and thermal vision. Missions gradually introduce new weapons, enemy types, environments, and multi-stage objectives. Health is limited, so positioning, stealth, and conserving ammunition are important.

Use cover and corners to reduce exposure, especially when facing heavily armed soldiers. Crouching can improve stability and makes it easier to approach some enemies without immediately attracting attention.

Conserve specialized ammunition and use the weapon best suited to each situation. Check rooms carefully for objectives, equipment, and evidence before moving on, because many missions require more than simply defeating every enemy.

Save thermal and night vision for areas where they are genuinely useful. When a mission gives a nonlethal objective or requires protecting a target, avoid indiscriminate explosives and confirm the objective before firing.
