I cannot win this sector at this moment. I must leave and go back, to hope for the enemie who has changed his place.

I try to bomb up TNT by shooting or grenades.

There is no directly way from sector G 7 to the sector G 5 (refinery). You have to go to F 7, F 6, F 5, G 5.

The price for the sap is now lower and your income is 25 % lower.

And it's possible that you must give up after playing not only a short time.

You have no chance - normaly - to get to know the secrets without playing one sector after the
other and to give up at some bad moments or you have good luck.

That's no criticism, only a statement.

Just I must see that I cannot leave the sector and go back because it's night and you cannot go into a sector which you don't have won (during the night).
