Jaranpat Khaejornbut has sent tips for the PSS war game. Among them he has spotted an omission from the instructions and a bug.

1. Something unusual happens with the cursor. If you leave it over a hex occupied by a unit at the end of your turn, it will have disappeared after the computer's turn. So before you press X to finish your turn make sure that the cursor hasn't been left over any of your units. You could place the cursor over the enemy's units and make your task that much easier.

2. The 'R' key has been omitted from the instructions but is very useful. It centres the cursor on the screen.

3. Don't rush into combat with enemies that have a higher efficiency rating. Try to cut their supplies first. When they're out of supplies, fatigue increases and affects efficiency. The efficiency display stays the same but its effect on the combat calculations will have altered and has considerable influence on the result.

To cut the enemy supply route find the weakest point in the line and attack it.

Once you've made a gap, units can move through it with less movement points .

Use the air mobile units and drop paratroopers behind enemy lines to help the attack. These units may have to be sacrificed but it's worth it.
