The BBC Micro version was the very first version of Jeremy Smith and Peter Irvin‘s classic Exile, released through Superior Software in 1988.
Yes, it has gaudy graphics, and yes: the gameplay takes some getting your head around, but Exile is undoubtedly a stunning piece of game design and world-building. Considering the limitations of the host machine.
At its core is a simple gravity game where you control a small spaceman. When you start exploring the caverns you begin to realise that there’s a whole ‘nother world out there. And some very annoying birds…
Exile is an extraordinary gaming achievement for a 32K machine. BBC Model B’s with more RAM could load an enhanced version of the game, with a larger playing area, sampled sound effects and digitised speech.
This classic BBC game inspired a whole series of side-scrolling shooters throughout the 1990s, and was re-made by its original creators several times for other platforms.
The even better Commodore 64 version, by the original programmers (with graphics by Paul Docherty), can be seen here.
