Developed during a competition inviting participants to adapt any Spanish arcade game on the ZX Spectrum, ALTAIR was first adapted on the Sinclair computer before being converted to the CPC. Released in 1981, the game recalls the concept of GALAGA but with the ability for your ship to move freely on the screen. You then face waves of enemy ships before taking on a boss protected by flying armour before you can destroy it. The game then repeats, allowing you to try and get the highest score.

Technically minimalist, ALTAIR remains effective despite its graphics from an earlier era. Some details show the author's will to faithfully reproduce the original arcade game, which increases the overall quality. The sound effects are unbearable after a few minutes, and on the contrary would have gained to be changed. The inability to fire backwards is also destabilising for the modern player, as the ship rotates according to direction. Repetitive and predictable, ALTAIR is a good representative game of its time despite the limitations it implies.
