Volfied

Volfied (ヴォルフィード) is an arcade video game designed by Fukio Mitsuji and released by Taito in 1989. It is a successor to Qix, with extra features and a futuristic science fiction aesthetic, rather than Qix's abstract geometry style; the player pilots a small spaceship named "Monotros" instead of a marker, and the enemies come in the form of various aliens.

Plot
Taking place in another galaxy, a space pilot is returning to his home world of Volfied, only to discover that it is under attack by an unknown alien force. The few remaining Volfied inhabitants are in an underground location of the planet and signal the pilot to their aid. The pilot flies to Volfied using his ship's defensive weapons in order to eliminate the alien threat and save his people.

Gameplay
The overall gameplay is identical to that of Qix, but the main enemy is no longer a collection of lines - instead it varies between levels, and is always accompanied by smaller enemies. When the player's spaceship succeeds in claiming a section of the level, the side containing the main enemy taken as "the outside". Any smaller enemies ending up on "the inside" are killed, resulting in point bonuses. In order to complete a level, the player must claim at least 80% of a level's area. Previously, the limits were 75% in Qix and 70% in Super Qix. Each level in Volfied has a unique background and enemies. As the player claims areas of the level the cleared area graphic is replaced with the graphic of the next level. Grey boxes also appear on the field — these give the player a random power-up when collected. Power-ups can grant the player speed or even weapons. There is a special completion bonus on certain levels, often attained by shooting the main enemy.
