Alien Gate (1993)

Alien Gate is a fixed shooter. Each stage consists of the player's ship facing off against a giant head that spawns several smaller enemies. Once all the required enemies are defeated, the player must defeat the head as a boss. The background gives the impression of a vertically scrolling shooter, but the attackers stay in position relative to the player's ship. There are 25 stages and 14 different enemy types.
