An absolute classic from the golden age of Spanish software, originally designed under Opera Soft S.A. in 1990 by José Vicente Pons, receives a definitive treatment in digital interactive preservation. "Mythos Plus Edition" is an ambitious and deep hardware enhancement overhaul developed by Enrique G. Gálvez for the Amstrad PCW line and next-generation compact systems like the PCW# mini. This version rescues a title historically bottlenecked by the commercial limitations of ancient office hardware, transforming it into a vibrant, high-octane arcade experience that pushes the Z80 architecture to unprecedented heights on the system.

The narrative plunges us straight into the dark corners of Greek mythology. Players take control of the mighty and swift centaur archer Ahyzar, the chosen champion of the god Krosar. Our divine mission is to infiltrate the heavenly peaks and subterranean vaults of Mount Olympus itself to retrieve seven stolen magical coins of divine power. This quest pits you against endless waves of nightmarish creatures, chimeras, spectral soldiers, and mythological guardians holding down every sector of the map via tactical flip-screen and scrolling platforming structures.

In stark contrast to the sluggish frame rates and dead silence of the original 1990 build, this "Plus Edition" features a massive engine rewrite: a drastically boosted execution speed and ultra-responsive controls have been injected into the game, turning traversal and platforming into a pure exercise of rapid reflexes. Visually, the game ditches its flat monochrome look to boast a striking "4 Infernal Colors" configuration, providing moody, high-contrast dithering and a sinister atmosphere to the sprites and levels of Olympus.

The sound department stands out as another great triumph of this preservation effort: it adds a full-length, in-game musical soundtrack that dynamically drives the pacing of your jumps and bow shots, completely supported by rewritten audio effects (FX) for every arrow hit, dodge, and enemy death. An essential piece of digital collector item that truly dignifies the Amstrad PCW library.
