You play Dash Rendar, a space trader/smuggler a-la Han Solo. In the Battle for Hoth, you fly a snow-speeder with Luke's Squadron. Blow up probes, walkers and AT-AT's over the frozen planetary surface. Loop your tow cable around their legs for extra bonuses.
This little number is the complete first level of the popular Nintendo 64 game, now ported to the PC. It also happens to be the best level in the game.
