Metal Spawn

In Metal Spawn, you use the keyboard to move your metal being left and right and fire at aliens as they move across the sky. Sometimes, when aliens die, they drop metal junk. You can pick these up for points but, more importantly, these allow you to spawn gun turrets. These gun turrets fire straight up and do not move but they also don't stop firing until they are destroyed. You have two types of aliens. The smaller ones more quicker and fire small, targeted shots. The larger ones are slower but better armored. Their shots are slower and fire straight down but are more powerful. To clear a level, you must destroy the required number of aliens. If you take too many hits on the upper part of your being, your health bar will deplete and you will die. If the time runs out, you also lose a life. Lose all your lives and the game is over.
