In 2992, mankind risks being swept away by the usual alien invaders. Space fighters piloted by artificial intelligence are unable to repel the attack. Therefore, it is necessary to go back to the old ways: a new class of vehicles, called "Redshift", driven by a human being. At the controls of the Redshift, you must drive the enemy out of five levels (galaxies), with three levels of difficulty, parallel universes populated by different foes. Only if you survive through the three universes, your mission will be accomplished.
Your spacecraft, at the start, is armed with a simple laser, but by eliminating aliens you obtain power-ups that will make your life easier. The Redshift also has a plasma shield available, which protects it from three impacts. You can also take advantage, for a limited number of times, of a support drone and an allied bombing, to aid you in the most difficult situations.
Ariel Ruiz, author of two very different masterpieces - Escuela De Ladrones and Carlos Michelis - never ceases to amaze, trying his hand at yet another game genre. The result does not disappoint expectations: Redshift is a real gem, a vertical scrolling shooter of excellent technical realization and great playability. Graphics and audio are on very high levels, scrolling is fast and smooth and the action is frantic but precise, as it should be the norm with this kind of game.
There is not much more to say, if not to play it without further ado: titles like this are certainly not seen every day on the Spectrum!
