Although the third-person controls are reminiscent of other shooters, they're not quite as polished. Sometimes you'll find yourself struggling to spin around in time to avoid death in one of the frequent and difficult boss battles, or you'll get stuck crouched behind a crate with no aiming options at all. Even with umpteen corridors and doorways to maneuver through, there's no effective way to breach a room, leaving you to poke your head in and run away constantly. It's a shame, because control is crucial to your success, and only rote memorization acts as a balm.
