This is a free game doesn't take long to download but its very fun. It has no story its a strange game.
Warning Forever is a 360-degree shooting game with vertical scrolling and an adjustable cannon that lets you control the direction and range of your fire. In this game, there are only two combatants--you and the boss ship. The more bosses you beat, the stronger they become. A time limit increases when bosses are defeated but decreases when you lose ships. Beat all the bosses you can before time runs out.
