Avenger

Avenger is a vertically-scrolling shooter, in which the player navigates a plane through levels populated by hostile planes, tanks, cannons, ships, stationary devices, and massive boss enemies. Before each mission, the player can choose among different weapons in three categories: main, sub, and special. Main and sub weapons are fired simultaneously and have unlimited ammunition, while the powerful special attacks are accessed by pressing a different button and are limited. The player can try any combination of the three categories, for example enhancing the main rocket launcher with a pod that fires laser to the sides as a sub weapon, and a protective shield as a special one.
