source: wikipedia_enShadowgate is a 1987 point-and-click adventure game developed by ICOM Simulations and published by Mindscape for the Macintosh as part of the MacVenture series. The game takes place in the Castle Shadowgate, residence of the evil Warlock Lord. The player, as the "last of a great line of hero-kings", is tasked with saving the world by defeating the Warlock Lord, who is attempting to summon the demon Behemoth out of Hell. The original Macintosh version was only in black-and-white, but color versions of the game were later released for the Amiga and Atari ST, and in 1989 for the Nintendo Entertainment System. The game was generally well-received, and was followed by several sequels and remakes for various systems.
