This game blew my mind when I played it on the Atari ST - a whole island to explore by ski, snowmobile and more, an invasion to repel and a ticking clock made it a challenge and one that beat me regularly.
Having it on GOG might give me that chance to finally beat it but to also overcome one of the issues the original game had which was the low frame rate that could make it hard to hit enemies at the best of times. Seeing it run smoothly now would do justice to a brilliant game.
