Gun-Reviper

Gun-Reviper is a 2.5D vertical-scrolling shooter with eight stages. You use powerful shots against enemies ahead and rotating options to attack enemies around you. Enemies above and below can be locked on to and destroyed with homing attacks; destroying several at once with homing earns a high score.

Combat and power

Bombs can cancel enemy bullets. Taking damage drains your ship’s energy, and running out of energy costs you a remaining ship and reduces your power by one level. Defeated enemies release energy or power-up items that restore energy or increase your power. As your score builds, your ship’s remaining power is added.

You can fire the main shot and sub-shot repeatedly by holding the shot button. Options are fixed in place while you fire, and you can collect up to six shot power-ups. Homing attacks target enemies you have locked on to and can be powered up to eight times. The Shield Bomb can also be powered up to eight times, but using it reduces its power by one. Saving it can help you pursue a high score, at the cost of increased difficulty.
