Chronicles Of Raynor

You move Raynor left and right with the arrow keys, aiming and shooting with the mouse. Enemy soldiers pour in from both sides of the screen, and you have to cut them down before they overwhelm you. Your main goal is to survive the assault and push forward through each stage. You collect ammo packs to reload your various weapons, which you can cycle through with number keys, and health pickups to stay in the fight. The pace is constant, with little respite between enemy waves, and the difficulty comes from managing your position and resources under that pressure. It feels like a tense, methodical grind against a steady tide of opponents.
