Alien Rupture

At the bottom of the board is a protected area with the player's ship, equipped with lasers to destroy obstacles and wandering pirate combat units horizontally. When an enemy reaches the end of the board or an obstacle, its ceiling is lowered and the player is more vulnerable to being hit by a missile and direct collision. In addition, each enemy shot down leaves behind a tombstone, which becomes an obstacle to be removed. The top of the screen shows the board number and the survival time remaining to complete the level.
