It is a pretty bland story, but does move the game along. The craft that you pilot can move in the X, Y and Z axes, and uses a HUD to supply you with information on what is going on around you. The damage model is very basic, with the craft either OK, damaged or totally sunk. In addition, there are no external views available for the ship that you are using, so there is no way to tell how badly you may be damaged. Amount of damage only seems to affect a very few flight systems and does not affect the manoeuvrability of the craft itself.
Graphics are clean and crisp.
The HUD that I referred to earlier is just not that informative, having only the most basic of information on it, such as speed, angle of attack, and depth. There are waypoint indicators also, but this comes into play mostly to point you in the direction of the bad guys. Overall, I found the HUD to be poor, and very hard to interpret. Torpedos travel for quite a distance, but they have no guidance system that I could determine. They tend to arc at the end of their run, so usually end up crashing into the sea floor when shot at far away targets.
