Shadow of the Beast takes place in a fantasy world where an Evil Lord called Maletoth kills Aabron's (our hero's) father and casts a spell to transform the young boy into a wild, strong and ugly beast (Aabron actually looks much like the ancient Greek god, Pan). Now Aabron must avenge his father's death and break the curse, gaining back his human nature. On his task, he must fight armed enemies, bloodthirsty monsters, magician lords, skeletons, avoid traps and finally confront the menacing Maletoth. The journey is hard and Aabron needs ample energy in order to survive. His only weapons are his bare hands plus some rare tools that he can use on the way. In terms of gameplay, Shadow of the Beast is one of the most difficult games ever created for the Atari ST so it takes patience and some good skills to survive. The whole action is pretty fast and the enemies are fiercely attacking to kill Aabron. But, apart from the enemy hordes there are also deadly traps, maze-like stages (etc the underground ones) and gigantic level bosses.
We all know that the Amiga and the Atari ST were rivals back in the mid-80's (and early 90's) and lots of games were ported directly from the Atari ST and were quite close in terms of graphics and details. Not this time though, since SOTB was ported from the Amiga to the ST. This game was always intended to run on an Amiga 500, since most of the other ports never really matched the original version. So, the Atari ST version cannot compete with the great Amiga version in any aspect. Atari ST's chips would only allow for 16-34 colors on-screen, 11-18 FPS of scrolling and sprite animation (which seems too slow compared to the constant 50 FPS of the Amiga version), 9 layers of parallax scrolling (versus 13 on the Amiga version) and so on. Also, the ST version suffers from some slowdown issues due to Blitter chip absence, especially when too many sprites are crowding the screen.
The sound is good though, at least as far as the original intro music is concerned. During gameplay the ST version does not offer any kind of music (the Amiga version offers plenty of quality tunes), except of a few SFX (but not digitized as in the Amiga version).
This version, although it fails to match the original and, leaving all comparisons aside, it looks OK on the Atari ST series, being technically an impressive ST game.
