The story of Aleste deals about the human-made Supercomputer, DIA 51, which has been infected by a hybrid virus and is spreading like wildfire, making it decide to eliminate the human race. When Yuri, Ray's girlfriend, gets injured in DIA's assault, Raymond Waizen has all the reasons in the world to get rid of DIA 51 once and for all in his Aleste fighter. The difficulty was noticeably higher. Known outside of Japan as Power Strike, Aleste was released in America as a mail-only limited edition game.
When I first played this game on a MSX, I was absolutely amazed by the graphics (especially the backgrounds) and the fluid animation of the sprites! I forgive the loose controls and high difficulty because of its great graphics (and sound)! The sound features a great chip tune at the introduction, and a few catchy sfx and soundtracks during gameplay. It is still a very well made bottom-up scrolling shooter with some nice bolt-on weapons and varied level graphics, and it definitely has the MSX2 quality to it!
