Old 8-bit owners won't need reminding about this one. Navy Moves was programmed by Spanish developers Dinamic, who were famous for pretty, multi-part arcade games with near-impossible difficulty settings. In fact, Navy Moves was one of them, and nothing's changed in this Amiga incarnation.
The first section of the game is an incredibly tricky Moon Patrol-type auto-scrolling sea-minefield kind of scenario, and it's so pointlessly and unbelievably frustrating that only the most determined "I've paid eight quid for this so I'm bloody well going to get some entertainment out of it" merchants among you will ever see the second bit. Of course, you can always skip straight to the second half of the game by using the cheat code conveniently supplied in the sealed envelope inside the box, but since doing that only gets you to a rather shabby and unexciting platform/puzzle game section, there doesn't really seem an awful lot of point.
Fair enough, you'll get plenty of life from this one, but since you'll spend most of the time cursing, swearing and generally not being very happy with life. It's debatable whether that's a good thing or not.
Personally, I get quite enough tension, frustration, annoyance and aggravation from my life as it is without adding any more to it when I play games, thanks very much.
Phenomenally irritating to start off with, and the rewards for perseverance aren't worth the effort. There are far too many good cheapies around this month to throw away cash on this.
