Conclusion: And, of course, there’s a standard 12 achievements for a total of 200 points. At the low end, you can add to your Gamerscore by completing your first rocket; at the top end, you get points for playing all 128 levels in single player. Much like Small Arms, there’s also a “viral” achievement that can only be snagged by playing a multiplayer game on Xbox Live with someone who’s already been “infected.” The main problem with the game is it’s somewhat one-dimensional.
Conclusion: The original Spectrum version is available to play within the game (called Retro mode) and has it's own achievement when you finish it - only 16 levels but I've haven't reached the end yet. So, to summarise, this is a nice update for fans of Jetpac but for many people they won't see or understand why Rare even bothered to release this. I rated it 4 stars (I'm a big fan of Jetpac and the ZX Spectrum) ... for others it would probably be 3 stars.
Excerpt: The original Jetpac from1983 is without a doubt one of the great titles from the transitional period that heralded the end of the golden age of arcade gaming. By the mid-eighties, crowded arcades packed with spotty kids and the smell of chips were a thing of the past, and games like Jetpac on the Sinclair Spectrum, which offered arcade gaming at home, were partly to blame.
