Space Courier is a methodical, medium-paced arcade shooter about avoiding asteroids, defeating cyborg aliens, and, of course, delivering packages.
You control the Courier's ship, The Priority, through a series of asteroid fields. Each field is more dangerous than the last, with an increase of asteroids and enemies.
Manage your fuel level, which depletes continuously and if you let it reach 0, your speed is greatly reduced. Picking up fuel cells along the way adds fuel to your battery. You'll also needs to keep an eye on your hull strength. When your hull reaches 0 you lose a life; lose all 3 and it's back to Level 1.
Every 5 levels you'll face a wave of enemies trying to stop you. The real challenge comes at level 15. Reaching level 20 makes you one the most skilled courier pilots this side of the Alpha Centauri.
