The game uses side-scrolling stages built around boss-driven progression. Players can choose X or Zero and swap between them during the campaign. X focuses on ranged shooting and armor upgrades, while Zero relies on close-range saber combat and mobility. Defeating stage bosses grants special weapons, and elemental weaknesses matter in both stage and boss planning. A 16-hour in-game timer tracks the Eurasia crisis, and completing certain tasks lowers the threat level. Endings vary depending on progress, rescues, and key outcomes.

X

One of the two main protagonists, specializing in ranged attacks and upgradeable armor.

Zero

The other main protagonist, built around fast close-range saber combat and agile movement.

Sigma

The series' main antagonist, continuing to menace the heroes in this entry.

Alia

Hunter support staff who provides mission analysis and radio guidance.

Douglas

A technical support engineer who handles armor and part-related upgrades for X.

Start by targeting stages whose boss weaknesses are easy to exploit, then use those rewards to make later areas simpler. With X, prioritize armor parts and charged shot accuracy; with Zero, practice dash timing, aerial movement, and combo rhythm. If the crisis timer is a concern, focus on missions that reduce the threat gauge before optional item hunting. Check walls and vertical routes for hidden parts and alternate paths.
