Interesting, if you have a large amount of jewelery, such as 200+ units, and sell them at a town like kulin or fort goks, you sell them at 4000 cash each, but you can buy then back at 700 cash. LOL
interesting bug:
if you click on the ammo on someone and click remove, then click on another item on the right side bar, and type in a large number, such as 100, you will have 100 of the second item you clicked, useful for armor, rocket launchers, and sniper rifles.
you have to talk to the sheriff and ask about desert patrol
then, go to verdammater platz and ask to join desert patrol.
when sheppard asks why, say you want to help out
