The Sentinel Description

The Sentinel also known as The Sentry is a 1989 strategy game from Firebird Software.Created by Geoff Crammond in 1986 for the BBC Micro and converted to Commodore 64, Spectrum, Amstrad CPC 464, Atari ST, Amiga and PC. It was among the first games, if not the first, to do solid 3D on home computers. While it ran acceptably fast on 16-bit computers, it was notoriously slow on 8-bit machines (its speed on the C64 was 3 seconds per frame). Despite this, it was played by many fans for years, some of which went as far as modifying their computers to enjoy it better (for example, by replacing the standard 1-MHz 6502 processor of their C64 with a model clocked at 16 MHz)

The game itself can be best described as an "energy management" game, it has a first person point of view and features ten thousand levels. Its uniqueness made it earn the definition of "first virtual reality game".

Graphically, the best version is the PC port, capable of VGA graphics and incremental lighting. This version, however, has very poor audio capabilities, since it only supports the PC speaker. The version with the best audio is the Amiga port, which features a soundtrack by David Whittaker.
