Missions take place on overhead maps containing rooms, corridors, terrain, enemies, and objectives. The player moves individual squad members, searches locations, uses weapons or equipment, and manages the team’s response to threats.

The objective varies by mission, but success generally depends on completing the assigned operation and preserving useful personnel and equipment. Turns allow the player to plan movement and attacks methodically; progression comes from completing missions and improving the squad’s operational capabilities.

Move cautiously and keep the squad together enough to support threatened units, while avoiding unnecessary exposure. Search the environment and manage ammunition and equipment before committing to prolonged fights.

Use cover and corners to limit enemy approaches, and spend actions on positioning when a clear attack is unavailable. Treat experienced or well-equipped soldiers as valuable resources rather than disposable units.
