CIDELSA can be considered as the first video game company in Spain. Their games are not a wonder, and certainly reflect market trends at that time, but they had some very interesting ideas.

It is clear that people of EFO loved Phoenix, because this recreation has many common points with the arcade of Amstar.

Destroyer is one of those shooter in which we have to go beyond a series of waves of different enemies. What primarily distinguishes Destroyer is the ferocity of the enemies whose attack us, especially talking about bullets, which go from being, simple straight shot with bullets in diagonal and in the later stages, the missile change course midway, becoming authentic devils, being much easier especially if we worry about the bullets and shoot just Gogo enemies.
If we can overcome with a little intuition and telepathic attacks, we will reach a stage where our ship is at the center of the screen and ships will come from anywhere on the screen, a real martyr for even the most skilled, is the typical phase that seems designed to suck us the coins.

Destroyer is a game that stands out especially in anything but the evil intentions of the enemy, but I will not complain, considering that we are talking about years ago.
