Missions are viewed from a behind-the-character perspective. Players infiltrate guarded areas, locate targets, collect items, and reach an extraction point while managing enemy awareness and stealth attacks.

Rikimaru and Ayame can use weapons, tools, hiding spots, and environmental routes. Progression is built around clearing missions and acquiring or using equipment; the game also includes customization and touch-screen interaction alongside its story missions.

Study patrol routes before moving, and avoid treating every guard as a required fight. Use shadows, corners, rooftops, and high ground to break lines of sight, then attack only when an enemy is isolated.

Save consumable tools for difficult guards or objectives. If a mission allows multiple routes, check the perimeter first; a slower approach is usually safer than crossing the center of a guarded area.
