Guttblaster

Guttblaster is a vertical shoot-'em-up in which the player controls a spaceship that needs to destroy all enemies on the screen to move on to a new level. Enemies can approach from all sides and some can only be destroyed by a certain type of ammunition. The ammo type can be changed by passing the ship over the circled numbers. The ammo consist of: (1) single bullets, (2) triple bullets, (3) round bombs that move in a circle around the spaceship and (4) bombs fired simultaneously in an up-and downward direction. It is not possible to choose from the ammo types, the last captured ammo remains in use until a new circled number has been picked.
