The game uses a side-view perspective across mission-based stages. Sam must infiltrate guarded locations, reach objectives, collect information, and escape while managing visibility and enemy encounters.

Players move through platforms, ladders, vents, and security areas. Progression is driven by completing story missions and using equipment or environmental cover to avoid or overcome guards. Stealth is encouraged, but direct combat is available when evasion fails.

Study guard routes before moving, and use darkness, cover, and elevated paths whenever possible. Avoid unnecessary fights because alarms and damage can make later sections harder.

Search side paths for useful items and information, and advance carefully through vents and security rooms. When stealth is no longer practical, use short attacks and reposition rather than staying exposed.
