Modern Scene

The Grand Prix modding community never stopped racing. The Sentinel has attracted fan ports and tributes. And in December 2025, MicroProse announced a collaboration with Crammond himself to bring the Grand Prix series back.

Grand Prix Modding Community

GP4 Season Mods (Annual)
ACTIVE

Developer: Grand Prix Games community contributors / Updated: annually

Each year, community modders release an update pack for Grand Prix 4 that replaces the 2001 season data with the current Formula 1 season. Updated liveries, driver names, team orders, and track adjustments are produced for every new season. The 2025 season mod was released on schedule. These mods run on top of the patched base game and require the community compatibility patch described on the Play page.

Sentinel Returns (1998)
COMPLETE

Developer: Cygnus Studios / Publisher: Psygnosis / Year: 1998 / Platforms: PC, PlayStation

The official sequel to The Sentinel, published by Psygnosis in 1998 for PC and PlayStation. Crammond is not credited as developer. The game uses a 3D engine appropriate to 1998 hardware and retains the core absorb-and-teleport mechanic. Reception was mixed - some players found the visual update improved the experience; others preferred the austere atmosphere of the original polygon landscapes.

Various Clones and Ports
WIP

Developer: various / Platform: modern browsers, iOS, Android

The Sentinel's gameplay model has attracted multiple fan implementations across the years. HTML5, Unity, and various mobile ports have appeared; quality varies considerably. The original BBC Micro game remains the reference version for purists and is the version documented by Mark Moxon's disassembly project.
