The player is given access to various menus which provide inventory insertions, detailed maps, and commands to unlock various parts of the station. By using the menus available, the player directs Rio into combat, solving puzzles, and interactions with NPCs. When Rio encounters one of the game's many monsters, combat ensues and the commands are given to direct Rio which enemy to fire at, which specific body part to fire upon, and when and where to maneuver. Combat perspectives switch between first-person and that of the cameras set about the station, with the latter more suitable for encounters of numerous foes.
