The Sentinel (US: The Sentry) is a
computer game created by
Geoff Crammond, published by
Firebird in 1986 for the
BBC Micro and converted to the
C64 (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
PC (by Mark Roll). It was among the first games to feature solid-filled
3D computer graphics on
home computers. While it ran acceptably fast on 16-bit computers, it was slow on 8-bit machines such as the C64, where the next view took up to three seconds to be precomputed. Despite this, the game retained a dedicated base of fans, some of whom were able to modify their computers to enjoy it better (for example, by using a
CMD SuperCPU in a standard 1-
MHz 6502 Commodore 64 to achieve
CPU clock speeds of 20 MHz).
