Ski & Shoot is a simulation of the Biathlon - the combination cross-country skiing and rifle shooting event that I first played a version of in Epyx's Winter Games on the Commodore 64 in (checks Wikipedia) 1986.
Where that was a primitive 2D affair, though, this is a fully 3D extravaganza for the Nintendo Wii. In both cases, however, I was reminded of Skeet Surfin' - the parody extreme sport invented for the movie Top Secret.
Ski & Shoot will make use of the balance board - balance being rather crucial to this sport and presumably use the WiiMote as a rifle or something. Check out these screens and see what you reckon.
