Have I gone all twizzley or something? I was sure that this was a Martech game a couple of years ago. Oh. I see, it was. Now out on Ricochet (coming back etc - geddit). Anyway if you like the sort of things that EK gets up to on his electroglide or whatever, you'll probably go for this. Graphically it's fairly dire, involving a stick man on bike (BMX push-bike to start, then moving on to a motorcycle) zooming along a white dotted line before shooting up a ramp and over some barrels. Easy controls coupled with an incredibly low skill requirement make Jump Challenge an affordable way to waste an hour or so.
