Astro Wars

Astro Wars is a shoot 'em up game that's very similar to Astro Fighter. The player controls a spaceship at the bottom of the screen and fights of waves of enemies coming form the top. Each wave has different enemy patterns and the fifth wave is a boss fight against a single enemy. The player loses a life when hit by enemy projectiles but can also run out of energy from firing shots. Energy is replenished after destroying the boss.
