Metroid

The Metroid series contains elements from shooter, platformer, adventure, survival and first-person games. The series is notable for its non-linear progression and solitary exploration format where the player only controls Samus Aran, with few or no other characters to interact with. The player gains items and power-ups for Samus's cybernetic suit primarily through exploration, and occasionally by defeating alien creatures through real-time combat with the suit's arm cannon. Many such upgrades enable further avenues of exploration. A recurring upgrade is the Morph Ball, which allows Samus to curl into a ball, roll into tight places and plant bombs. Another well-known recurring ability is the Shinespark, which enables Samus to charge her Power Suit with energy, and run and dash at tremendous speeds from a running start. The Power Suit, thus empowered, can break through certain walls.
