This one's ancient, but it's still a contender for the best Spectrum race game ever. As I remember, it was the first racer to use the hill technique, and the jumps have never been repeated successfully since. Rev that bike and take it through all the levels, over dusty mountain tracks, tarmac courses and desert trails. You have to complete each track within the set time limit to progress on to the next level.
Enduro Racer isn't the easiest of biking games, I still find it difficult to get past the third level (but that says more about my game playing skill, I suspect!). Gameplay retains a big challenge throughout -and still looks and plays well after all these years, which can't be bad! Great fun, graphically impressive and varied, well worth buying, especially on budget.
