Assault Squadron

Assault Squadron is a shooter of the "bullet hell" variety. The story is that the player needs to avoid an alien invasion by shooting all of them dead. In each of the six levels (which switch between vertically and horizontally scrolling), the player needs to survive long enough to reach the end and beat a boss battle. The problem with this is that there are a lot of enemies which unleash a lot of projectiles which the player should dodge in order to avoid defeat.

Before each level, the player gets to choose between one of three difficulty level (which affect the number of enemies and continues) and one of four space ships which differ in handling and weapon configuration. But of course one of the most important task is to upgrade the ship with special weapons so it stands a chance against the opposition, but after losing a life it reverts to the basic setup. Besides simply beating the levels, another challenge is acquiring a place on the online high-score list by using combo attacks. The ship can be either controlled by touch 1:1, touch 2.5:1, tilting or an virtual joystick.
