Hellfire

What sets this shooter apart from many other horizontal space shooters is that you choose the direction of your shots at any time between forward, backward, upward+downward and 4-way diagonal. The 4-way diagonal shot is usually the most effective and makes for some interesting gameplay setups, such as stationary guns you can only reach by passing them (while avoiding their shots) and then placing yourself diagonally above them. There is also a bomb to take out multiple enemies. The game has a standard set of pickups: P icons for powering the weapons, S icons for increasing ship speed, B icons for bombs, and score icons.

There is not much of a plot in this game, you arrive by a dropship, only to face a large number of enemies at once, and you fly through each level trying to take everything out, R-Type style.
