The Sentinel

The Sentinel, released in the United States as The Sentry, is a puzzle video game created by Geoff Crammond, published by Firebird in 1986 for the BBC Micro and converted to the Commodore 64 (by Crammond himself), Amstrad CPC (with a cross-compiler written by Crammond), ZX Spectrum (by Mike Follin), Atari ST, Amiga (both by Steve Bak) and IBM PC compatibles (by Mark Roll). The Sentinel was among the first games to use solid-filled 3D graphics on home computers. It won numerous awards upon release and has since appeared on several "best video games of all time" lists. The IBM PC port supports VGA graphics, with an additional lighting effect: objects and terrain become darker the farther away they are from the point of view. The Amiga port has a sampled soundtrack by David Whittaker. Gameplay In The Sentinel, the player takes the role of a Synthoid (called just "robot" in the US version), a telepathic robot who has to take control of a number of surreal, checkered landscapes of hills and valleys, by climbing from the lowest spot, where the hunt begins, to the highest platform, over which the Sentinel looms.
