If you only ever buy one PD game, buy this! No, I'm serious, it's such a good game that I even tried to get Andy to let me review it as a full page jobbie (only we didn't have enough room!) send off your money now! (Alright. Steady thy sword, lad! Andy).

I don't really know why Aquanaut has captured my heart so, but I wouldn't be surprised to find that deep down inside my brain's basements, there's a happy link with the past being made between this game and some of my old Spectrum favourites. Let's just say that anyone who's ever played Excelon or Cybernoid will probably twinkle when they see the graphical style the game employs.

The gameplay itself is nothing we haven't seen before, but is somehow constructed in such a way as to reward you just often enough to keep you playing - if only to see what comes next. Fortunately, you want to keep playing anyway, so this is just an added bonus!

The game itself pits you as the pilot of an underwater exploration craft working through a number of slightly different missions. As in all classic games of the 80s, there are a set number of targets spread across a selection of large and sprawling levels, with lots of hostages to be rescued, enemy mines to be destroyed, etc. etc.

You start off with a fairly basic craft, but by shooting what look like tins of cat food and then collecting their icon-ed contents, various additional weapons can be collected, along with power-ups for your standard gun. Missiles, depth charges and rebounders are some of the toys on offer here, but must be used wisely as certain obstacles can only be breached with such doobies.

Once all of the targets have been collected-or destroyed, you're directed to the level's exit, where an end-of-level baddy is waiting to take your coat and hat (not to mention your legs and lower torso).

I know it all sounds fairly normal but the baddies, level graphics, weapons, map layout and, well, everything really, have either been planned perfectly, or have accidentally fallen into place. It took me two days of playing to get through all three levels on this disk, and for £3.99 I find it hard to fault. Get your money out now! (Hmm... objective, my dear Matthew, you are not - Harry).
