Now hear this! Now hear this! All hands man your battle stations.
Enemy submarines have been detected in your waters. You command a destroyer which can launch as many as four depth charges at a time. Your mission is to sink as many enemy subs as possible.
But it's not that simple. Because SUB-SCAN is more than a shooting match. It's a game of strategy. A battle of wits. Can-and-mouse on the high seas between the hunter above and the hunted below.
* Your main mission is to hit all the subs. Miss ten and the game is over.
* Once you have aimed a depth charge at a particular sub, keep your eye on the depth charge and the sub. A shallower sub might cruise into the battle scene and run into a previously targeted depth charge. In this case you’ll need to quickly launch another depth charge to hit your original target sub.
* Avoid hitting the BONUS SUB as long as you possibly can! This builds the bonus value up at an incredible rate and keeps the subs moving at a manageable speed. Remember: a BONUS SUB never counts as a missed sub if you let it go.
* Use the viewport. If you time it right, you can hit subs just as they enter the battle scene.
