Metroid Prime Hunters: First Hunt

Metroid Prime Hunters: First Hunt is a demo of the then-upcoming Metroid Prime: Hunters for the Nintendo DS handheld, that came bundled with the console when it launched.

Gameplay
Metroid Prime Hunters: First Hunt has no story; instead, it features a set of disconected training missions designed to showcase various aspects of gameplay. The single-player portions of the game feature a scoring system; points can be gained by defeating enemies, and combos activated by ensuring that all shots hit their targets.

Regulator
The Combat Regulator features a linear series of challenges which Samus must complete in under 10 minutes. The level takes place in an environment that resembles the Celestial Archives area from the finished game, and features a variety of enemies, platforming challenges, and a morph ball maze, and finishes off with a boss fight against a doppelgänger.
